一般描述

4-羟基苯甲酸丙酯 (PHB) 是一种 p -羟基苯甲酸酯衍生物。它可在酸性离子液体存在下由 p -羟基苯甲酸与 n -丙醇反应来制备。它在单斜晶空间群 P2 1 /c 中结晶。据报道，它是一种内分泌干扰化合物。

应用


  • 盐酸罂粟碱溶液的光稳定。：该研究考察了4-羟基苯甲酸丙酯对盐酸罂粟碱溶液光稳定性的影响。该研究强调了4-羟基苯甲酸丙酯作为防腐剂的功效，为其在药物中的潜在应用提供了启示，其中光诱导的化合物降解是一个关注的问题。这一发现对于提高药液的保质期和稳定性具有重要意义（Piotrowska K et al., 2010）。

This study presents a method for one-step formation of poly(ethylene oxide) nanofibers incorporating nanoparticles of a poorly water-soluble compound. Using the new method reported here, nanofiber-nanoparticle composites are fabricated in one step by electrospinning of an oil-in-water microemulsion, in which

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.
