General description

El ácido bórico es un ácido de Lewis monobásico débil (aceptor de pares de electrones), que reacciona reversiblemente con los alcoholes. Se utiliza en productos de higiene dérmica y femenina debido a sus suaves efectos antibacterianos y antifúngicos. El ácido bórico se utiliza como amortiguador en productos oftálmicos. Actúa como un lubricante sólido eficaz debido a su estructura molecular. El ácido bórico encuentra sus aplicaciones en la fabricación de vidrio, como retardante del fuego. El ácido bórico se utiliza en bioquímica en disoluciones tampón. También forma equilibrios complejos en disolución, siendo el ion tetraborato (B4O7 2- ) la especie predominante. Los tampones de borato intervienen en los sistemas de electroforesis discontinua y electroforesis capilar para la separación de proteínas y ácidos nucleicos.

Application

El ácido bórico se ha utilizado:
  • para preparar tampones borato destinados a la cuantificación de aminas primarias en la superficie de nanocápsulas
  • para estudiar sus efectos sobre el cambio epigenético
  • para la estimación de proteínas en pasto de trigo utilizando el método Kjeldahl

Se utiliza para promover las amidaciones de los ácidos carboxílicos y las aminas en cantidades catalíticas. Esta tecnología evita el requisito de preactivación del ácido carboxílico o el uso de reactivos de acoplamiento.

Questions

1–3 of 3 Questions  

  1. 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

  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.
