一般說明

乙醇酸(羟基乙酸)是一种α-羟基酸。浓度为70%,pH范围为0.08-2.75的乙醇酸溶液被广泛用作表面化学剥离剂[1]目前已经制备出多种乳酸和/或乙醇酸(低分子量)的低聚物或聚合物。[2]乙醇酸可通过植物组织偶联的流动注射化学发光生物传感器进行测定,该传感器既可用作基于植物组织的生物传感器,也可用作化学发光流体传感器。[3][4]

應用

乙醇酸(羟基乙酸)已用于制备PLGA-PEG-PLGA共聚物(PLGA = 聚乳酸聚乙醇酸共聚物,PEG =聚乙二醇)。[5]

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.
