Description générale

1-Methoxy-2-propanol (Propylene glycol methyl ether, PGME), a glycol ether, can be synthesized by reacting propylene oxide with methanol in the presence of ZnMgAl (zinc-magnesium-aluminium) catalysts.[1] Its degradation by microorganisms in different soil types has been investigated.[2] An oral reference dose (RfD) and an inhalation reference concentration (RfC) values of PGME have been obtained from inhalation studies in F344 rats and B6C3F1 mice.[3]
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry.Monoethers, especially propylene glycol methyl ether (PGME), are widely used as pollution-free solvents in fine chemical synthesis in pharmaceutical, chemical and cosmetic industries and thus aligns with "Safer Solvents and Auxiliaries".

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).

Des solvants biorenouvelables

Pourquoi devrait-on choisir entre solvants écologiques et solvants fiables ? Nous vous proposons les deux à la fois grâce à nos solutions biorenouvelables et plus écologiques. Le solvant Cyrene™ est une nouvelle alternative aprotique dipolaire aux solvants courants frappés par la restriction REACH, tels que la N-méthyl-2-pyrrolidone (NMP) et le diméthylformamide (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.

  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
