General description

Dimethyl maleate is a dienophile used as a chemical intermediate to synthesize dienes, plastics, and copolymers.[1]

Dimethyl maleate (DMM) is a reactive dienophile and undergoes ultrasonic irradiation promoted Diels-Alder reaction with substituted furans.[2] Mesoporous siliceous SBA-15-supported Cu catalyzed gas phase hydrogenolysis of DMM to 1,4-butanediol (BDO) has been reported.[3] Aluminium chloride has been reported to accelerate the Diels-Alder reaction of DMM and anthracene.[4] DMM can be synthesized by the esterification of maleic anhydride with sulfuric acid and methanol.[5]

Application

  • Dissociation of bovine 6S procarboxypeptidase A by reversible condensation with 2,3-dimethyl maleic anhydride: application to the partial characterization of subunit III.: This study explores the dissociation of bovine procarboxypeptidase A using 2,3-dimethyl maleic anhydride, highlighting its applications in the partial characterization of enzyme subunits. The research demonstrates the potential of dimethyl maleate derivatives in protein chemistry and enzyme structure studies. (Puigserver and Desnuelle, 1975).

Many restoring formulations for damaged hair keratin have been developed. Some patents claim that the hair repair occurs through the reconstruction of disulfide bridges of keratin, through α,β-unsaturated Michael acceptors, such as shikimic acid and bis-aminopropyl diglycol dimaleate. To gain

Based on (1)H NMR studies, subtle electronic factors rather than pre-organisation dictate the binding stoichiometry of the new, norbornene based, anion hosts 1 and 2 with acetate, however, the binding of dihydrogenphosphate appears to be based solely on steric constraints.

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.
      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
