About Terazosin-d8

Listed under CAS 1006718-20-2, Terazosin-d8 is a stable isotope labelled analogue related to Terazosin available from Vaqora Chemicals. Its molecular formula is C19H25N5O4 and its molecular weight is 395.5 g/mol. The IUPAC name is [4-(4-amino-6,7-dimethoxyquinazolin-2-yl)-2,2,3,3,5,5,6,6-octadeuteriopiperazin-1-yl]-(oxolan-2-yl)methanone. Common synonyms include Terazosin (piperazine D8) and TMIJ-0183.

It is supplied as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. 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.

We offer Terazosin-d8 in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
