About Diethyl Phthalate-D4

Listed under CAS 93952-12-6, Diethyl Phthalate-D4 is a stable isotope labelled standard available from Vaqora Chemicals. Its molecular formula is C12H14O4 and its molecular weight is 226.26 g/mol. The IUPAC name is diethyl 3,4,5,6-tetradeuteriobenzene-1,2-dicarboxylate. It is also known as Diethyl Phthalate-3,4,5,6-d4 or Phthalic acid, bis-ethyl ester D4.

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Good laboratory practice and suitable PPE are recommended during handling.

Its mass shift relative to the unlabelled analyte makes it a dependable internal standard for LC-MS/MS assays, improving accuracy in bioanalysis, therapeutic drug monitoring and method validation. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Vaqora Chemicals supplies Diethyl Phthalate-D4 in 10 mg, 25 mg, 50 mg and 100 mg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
