一般描述

碳酰氯可用作有机合成中的试剂，用于各种反应，如羰化反应和异氰酸酯合成。碳酰氯是在自由基诱导的氯代烃降解过程中产生。[1]研究人员已经报道了使用热解吸（TD）及气相色谱-质谱（GC-MS）测定空气样品中的碳酰氯。[2]

应用

碳酰氯溶液可用于合成以下物质：
  • 磺酰氯[3]
  • Fmoc（芴基甲氧基羰基氯）-十八烷基磺酰氯[3]
  • O-苄基-L-丝氨酸羧酸酐[4]
碳酰氯溶液（15 wt. %，以甲苯为溶剂）已被用于合成以下肽单体：
  • γ-(4-炔丙氧基苄基)-L-谷氨酸N-羧酸酐（POB-L-Glu-NCA）[5]
  • γ-(4,5-二甲氧基-2-硝基苄基)-L-谷氨酸 N-羧酸酐（DMNB-L-Glu-NCA）[6]
  • γ-(4,5-二甲氧基-2-硝基苄基)-D-谷氨酸盐 N-羧酸酐（DMNB-D-Glu-NCA）[6]
  • 2-硝基苄基(4-乙烯基苯基)氨基甲酸酯[7]

包装

推荐将25毫升安全/密封™瓶作为一次性使用的瓶子。重复穿刺可能会导致产品性能下降。

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.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  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
