一般描述

1-甲氧基-2-丙醇(丙二醇甲醚，PGME)，是一种甘醇醚，可通过在ZnMgAl（锌-镁-铝）催化剂存在下由环氧丙烷与甲醇反应进行合成。[1]它在不同土壤类型中的微生物降解已被研究。[2]通过对F344大鼠和B6C3F1小鼠的吸入研究，已得到PGME的口服参考剂量（RfD）和吸入参考浓度（RfC）值。[3]
我们致力于为您提供更环保的替代产品，以符合“绿色化学的 12 项原则”的一项或多项原则要求。单醚，特别是丙二醇甲醚（PGME）作为一种无污染溶剂已广泛应用于制药、化工和化装品行业的精细有机合成应用中，符合“更安全的溶剂和辅助剂”的要求。 点击此处了解更多信息。

Glycol ethers still continue to be a workplace hazard due to their important use on an industrial scale. Currently, chronic occupational exposures to low levels of xenobiotics become increasingly relevant. Thus, sensitive analytical methods for detecting biomarkers of exposure are

REACH requests the exploration of alternative strategies for hazard identification before resorting to (in vivo) testing. Here, we combined read-across as non-testing strategy with a tiered exposure assessment for the risk characterisation of 1-methoxypropan-2-ol (PGME) as a representative for phase-in

Biorenewable Solvents

Why should you have to choose between solvents that are ecological and those that are reliable? Enjoy both at once with our biorenewable and greener solutions. Cyrene™ solvent is a new dipolar aprotic alternative to common REACH restricted solvents, such as N methyl-2-pyrrolidone (NMP) and Dimethylformamide (DMF).

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
