Application

BSTFA (with 1% TMCS) may be used as a derivatizing agent in the following:
  • Analysis of estrogenic compounds in water samples using gas chromatography coupled to mass spectrometry (GC-MS).
  • Quantification of α-pyrrolidinovalerophenone (α-PVP) and its metabolites in urine samples using gas chromatography coupled to mass spectrometry (GC-MS).

Features and Benefits

  • BSTFA is very versatile, reacting with a range of polar organic compounds and replacing active hydrogens with a −Si(CH3)3 (trimethylsilyl) group.
  • Reacts rapidly and more completely than BSA.;
  • TMCS increases the reactivity of BSTFA (or other silylation reagents).
  • Amides and many secondary amines and hindered hydroxyls, incompletely derivatized by BSTFA alone, can be derivatized by adding 1-20% TMCS to BSTFA.
  • Has good solvent properties and can function as a silylation reagent without additional solvents.
  • Alternatively, the mixture is very soluble in most commonly used silylation solvents.

Questions

1–2 of 2 Questions  

  1. 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.

  2. 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
