Descrição geral

N,N′-Dimethylthiourea, also known as 1,3-Dimethylisothiourea, is commonly used in organic reactions to synthesize N-containing compounds such as N-acyl-substituted 1,1-diaminoethylenes, amidines, ureas, and thioureas. [1] [2]It also acts as a nucleophilic catalyst in the bromination of alcohols using N-bromosuccinimide (NBS), during the conversion to the corresponding bromides. [3]

Aplicação

  • Pharmaceutical Analysis: Mao et al. developed an itaconic acid-based organic-polymer monolithic column for hydrophilic capillary electrochromatography, which was used in pharmaceutical analysis. N,N′-Dimethylthiourea could be utilized to improve the column′s performance by acting as a potential organic modifier to enhance the separation processes (Mao et al., 2024).
  • Agricultural Research: Li et al. examined the effect of the reactive oxygen scavenger N,N′-Dimethylthiourea on seed germination and radicle elongation of maize. This research could help in understanding how this chemical can be used to influence plant growth under stress conditions, potentially improving agricultural productivity (Li et al., 2023).

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
