Alfuzosin

About Alfuzosin

Alfuzosin is a high-purity reference standard of Alfuzosin carrying the CAS registry number 81403-80-7. Its molecular formula is C19H27N5O4 and its molecular weight is 389.4 g/mol. Its systematic (IUPAC) name is N-[3-[(4-amino-6,7-dimethoxyquinazolin-2-yl)-methylamino]propyl]oxolane-2-carboxamide. It is also known as Alfuzosine or alphuzosine.

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. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this Alfuzosin standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Our customers for this product work in 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.
