一般描述

柠檬酸一水合物 (CAM) 是一种有机酸。在柠檬酸合成过程中，可在 20-25℃ 下从柠檬酸溶液母液中结晶制得。[1]据报道，其水溶液的摩尔焓为 δ 溶胶Hm (298.15K, m = 0.0203molkg-1) = (29061±123)Jmol-1。[2]对其晶体生长动力学的研究表明，生长与尺寸呈线性关系。[3]

应用

可使用柠檬酸一水合物：
  • 采用 68 Ga 预纯化和放射性标记技术的丙酮法制备柠檬酸溶液。[4]
  • 制备用于细菌酶电泳的 Tris-柠檬酸盐缓冲液。[5]
  • 提高盐酸地尔硫卓从熔融挤出骨架片中的释放度。[6]

Questions

1–2 of 2 Questions  

  1. 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

  2. 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.
