Descripción general

El peróxido de hidrógeno (H2O2), un antiséptico tópico, se sintetiza en las células aerobias como un subproducto de la respiración aerobia. También puede producirse como un producto de salida de reacciones enzimáticas en peroxisomas, mitocondrias u otros compartimientos celulares.

Aplicación

La disolución de peróxido de hidrógeno se ha utilizado para:
  • tratar las células epiteliales nasales para ensayos de sensibilidad al H2O2
  • tratar la línea de células inmortales de queratinocitos humanos (HaCaT) y la línea celular de melanoma humano (GLL19) para inducir senescencia
  • incubar cortes cerebrales para la tinción de bromodesoxiuridina (BrdU)/NeuN
  • en el ensayo de proliferación celular, para incubar células madre neuronales (NE-4C) destinadas a experimentos in vitro

Acciones bioquímicas o fisiológicas

El peróxido de hidrógeno (H2 O 2) se utiliza principalmente en la limpieza de heridas. Puede matar los patógenos mediante un estallido de la oxidación y la producción de oxígeno local. El H2O2 funciona como una molécula de comunicación o segundo mensajero. Desempeña un papel clave en la expresión génica de muchas maneras. El H2O2 participa en la modulación de la inflamación.

Questions

1–10 of 19 Questions  

  1. How much we need to add 30% H2O2 in 1mL of solution(water as solvent) to make100mM molarity?

    1 answer

    1. The molarity of this product is calculated to be 9.791 M based on a density of 1.11 g/mL, a formula weight of 34.01 g/mol, and a concentration of 30 w/w%. Here is the calculation:
      Molarity = Density x concentration x 1000 / formula weight = 1.11 x 0.3 x 1000 / 34.01 = 9.791 M.

      To make a 100 mM solution, use the Dilution Formula: C1V1 = C2V2 to find the volume V1 of the 30% H2O2 solution needed.
      C1 = 9.791 M (concentration of the stock solution)
      C2 = 0.1 M (desired concentration)
      V2 = 0.001 L + V1 (final volume, which is the sum of 1 mL of water and the volume of H2O2 added)

      Rearrange the formula to solve for V1:
      9.791 x V1 = 0.1 x (0.001 + V1)
      V1 = 0.1 x 0.001 / (9.791 - 0.1) = ~0.0000103 L = ~10.3 µL

      Therefore, approximately 10.3 µL of this product is required for a 100 mM H2O2 solution when mixed with 1 mL of water.

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  3. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  5. how can we determinate H2O2 concentration in case of 30% by titration , i found way to do this with sodium thiosulfate but they mentioned that is for 0.1% - 5 % con. - can i use it ?

    1 answer

    1. Using a procedure meant for lower concentrations of hydrogen peroxide may lead to less accurate results. Solvay chemicals has a method for determination of the concentration of hydrogen peroxide (20-70%) by titration with potassium permanganate solution: https://www.solvay.com/sites/g/files/srpend221/files/2019-10/H2O2%20Determination%20of%20Hydrogen%20Peroxide%20Concentration%20-20%20to%2070-.pdf

  7. Hi, I would like to get information on this product (H2O2 Cat # H1009-5ML) for Lot numbers MKCL6061 and MKCJ1034 to know their expiration dates. Please help me get this information. Thanks.

    1 answer

    1. This product is not assigned an expiration date. It is assigned a recommended retest date of approximately one year after the quality release date. A recommended retest date is the time during which the product is expected to remain within established stability specifications, provided that it has been stored under defined conditions. After the Retest Date, product samples should be examined to ensure that the product is still in compliance with the established specifications.

  8. how much we need to add 30% H2O2 in 7ml of solution(water as solvent) to make 5mM molarity....could you please tell with calculation?

    1 answer

    1. The molarity of this product will change slightly from lot to lot, based on the final concentration. The concentration range is 29 - 32 %. The molarity can be calculated using the basic equation (density in g/L x final percentage)/molecular weight. The molarity of a 30 % solution of this product can be calculated by the following:
      (1110 g/L X 0.30) / 34.01 = 9.79 M.

      The volume of product required to prepare 7 mL of 0.005 M H2O2 would be 3.6 ul. For ease of pipetting, it may be more practical to prepare a larger volume. For example:
      Use 3.6 uL to prepare 7 mL at 5 mM
      Use 7.7 uL to prepare 15 mL at 5 mM
      Use 10.3 uL to prepare 20 mL at 5 mM

      Alternatively, an intermediate working solution can be prepared that would require further dilution.
      To prepare a 1 M stock from the 9.79 M concentrate, a dilution may be prepared using the M1V1 =M2V2 formula.
      In this case, 1.02 mL of the 9.79 M stock is diluted to 10 mL to achieve a 1 M concentration.
      From the 1 M solution dilute 0.035 mL (35 ul) to a final volume of 7 mL to achieve a 5 mM concentration.

  9. 30% is w/w ratio or its w/v ratio and can you give formula to calculate molarity of this H2O2 30% solution?

    1 answer

    1. As stated on the product detail page, this is hydrogen peroxide 30% w/w in H2O.

      The molarity of this product will change slightly from lot to lot, based on the final concentration. The concentration range is 29 - 32 %. The molarity can be calculated using the basic equation (density in g/L x final percentage)/molecular weight. The molarity of a 30% solution of this product can be calculated by the following:
      (1197 g/L X 0.30) / 34.01 = 9.79 M

  10. How do I check the concentration of H2O2 for a solution that has been stored at 4 degrees Celsius for about a year? Do I check the absorbance at 240nm?

    1 answer

    1. The product concentration is 30 % (w/w) in H2O. This product has a shelf life of approximately 2 years. The concentration of this product is determined by iodometric titration. See the link below to review an application note provided by Mettler Toledo: https://www.mt.com/us/en/home/supportive_content/ana_chem_applications/titration/M860.html
