一般描述

N,N′-二甲基硫脲,又称1,3-二甲基异硫脲, 常用于在有机反应中合成含氮化合物,包括N-酰基-取代1,1-二氨基乙烯类、脒、尿素和硫脲。 [1] [2]还在醇的溴化反应中用作亲核催化剂,该反应在转化为相应溴化物时使用N-溴琥珀酰亚胺(NBS)。 [3]

应用

  • 药物分析:Mao等人开发了一种用于药物分析的亲水毛细管电色谱的衣康酸基聚合物整体柱。N,N′-二甲基硫脲可作为潜在的有机改性剂来改善柱′性能 ,改善分离过程 (Mao et al., 2024)。
  • 农业研究:Li 等人考察了活性氧清除剂N,N′-二甲基硫脲对玉米种子萌发和胚根伸长的影响。该研究可能帮助我们理解该化合物如何在应激条件下影响植物生长,可能改善农业生产率 (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
