About Carebastine-D5

Listed under CAS 1189661-02-6, Carebastine-D5 is a stable isotope labelled analogue related to Ebastine available from Vaqora Chemicals. Its molecular formula is C32H37NO4 and its molecular weight is 504.7 g/mol.

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.

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.
