About Clozapine-d4

Clozapine-d4 (CAS 204395-52-8) is a stable isotope labelled analogue related to Clozapine offered by Vaqora Chemicals. The compound has the formula C18H19ClN4, corresponding to a molecular weight of 330.8 g/mol. Systematically, it is named 3-chloro-6-(2,2,6,6-tetradeuterio-4-methylpiperazin-1-yl)-11H-benzo[b][1,4]benzodiazepine. Common synonyms include Clozapine-d4 (4-methylpiperazinyl-2,2,6,6-d4).

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

This isotope-labelled compound is used as an internal standard for LC-MS and LC-MS/MS quantitation of Clozapine and related analytes in bioanalytical, pharmacokinetic and impurity studies. 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.
