Descripción general

Methoxyamine hydrochloride is a commonly used reagent for the generation of oxime derivatives of aldehyde- or ketone-group containing compounds. It is typically employed as an oximation reagent prior to silylation derivatizations.[1][2]

Aplicación

Methoxyamine hydrochloride can be used as:
  • A reagent for the preparation of O-methyl oximes.
  • A reagent used to make O-methyl oximes from aldehydes or ketones.
  • An alkylation reagent.
  • It may be used as a derivatization agent to improve the sensitivity of opioids,[3][4] steroids[5] and ionic metabolites[6] in biological samples and non-volatile flavor compounds in "Angeleno" plum fruit[7] prior to the determination of analytes using gas chromatography-mass spectrometry (GC-MS) technique.

Questions

1–2 of 2 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.
