About Diphenhydramine

Vaqora Chemicals supplies Diphenhydramine, a high-purity reference standard of Diphenhydramine registered under CAS number 58-73-1. Its molecular formula is C17H21NO and its molecular weight is 255.35 g/mol. Its systematic (IUPAC) name is 2-benzhydryloxy-N,N-dimethylethanamine. Alternative names: Benzhydramine and Alledryl.

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. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

As a reference sample of Diphenhydramine, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. 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.
