About Nordoxepin-d3 Hydrochloride

Vaqora Chemicals supplies Nordoxepin-d3 Hydrochloride, a stable isotope labelled analogue related to Doxepin registered under CAS number 1331665-54-3. Formula C18H20ClNO, molecular weight 304.8 g/mol.

It is supplied as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. Under GHS it is labelled “Warning”, so handle it with suitable PPE and consult the SDS.

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.
