General description

Thioacetamide is a thiocarboxamide used as a crosslinking agent for polymers, chemical reagents, and catalysts.[1]

Thioacetamide is a thiocarbonyl compound. It undergoes deuterium exchange reaction with D2O to afford N-dideuterated thioacetamide. Infrared spectral investigations of thioacetamide and its deuterated derivative (N-dideuterated thioacetamide) have been reported.[2]

Application

Thioacetamide may be used as a source of sulfur required for the synthesis of CdS nanoparticles in PVA (poly (vinyl alcohol)) solutions.[3] It may be used in the preparation of sulfur precursor stock solution, which was required during the synthesis of CdS quantum dots in PVA-COOH (carboxylic acid functionalized poly(vinyl alcohol)) and EPC (Enzyme-Polymer Conjugate) solutions.[4]
Thioacetamide may be used in the preparation of Sb(TA)2Cl3, a precursor for oxide-free stibnite.[5] The addition of TA during the synthesis of visible-light activated titanium dioxide photocatalysts led to an increase in its photocatalytic activity.[6]

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
