About Dioctyl maleate

Dioctyl maleate is an API impurity reference standard carrying the CAS registry number 2915-53-9. Formula C20H36O4, molecular weight 340.5 g/mol. Systematically, it is named dioctyl (Z)-but-2-enedioate. Common synonyms include Di-n-octyl maleate and dicaprylyl maleate.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. It carries the GHS signal word “Warning” with 1 hazard statement. Review the Safety Data Sheet before use.

Pharmaceutical QC and development laboratories use this impurity standard of the parent drug substance to develop and validate HPLC methods, to set specification limits and to document impurity profiles in ANDA and DMF submissions. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
