About Benzyl Butyl Phthalate-d4

Vaqora Chemicals supplies Benzyl Butyl Phthalate-d4, a stable isotope labelled standard registered under CAS number 93951-88-3. With the molecular formula C19H20O4, it has a molar mass of 316.4 g/mol. Systematically, it is named 2-O-benzyl 1-O-butyl 3,4,5,6-tetradeuteriobenzene-1,2-dicarboxylate. Common synonyms include Benzyl n-butyl phthalate-3,4,5,6-d4 and Phthalic acid, benzylbutyl 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. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

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. It is used across 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.
