About Piroxicam EP Impurity F

Piroxicam EP Impurity F (CAS 76508-37-7) is a pharmacopeial impurity of Piroxicam offered by Vaqora Chemicals. Its molecular formula is C12H13NO5S and its molecular weight is 283.3 g/mol. Its systematic (IUPAC) name is propan-2-yl 2-(1,1,3-trioxo-1,2-benzothiazol-2-yl)acetate. It is also known as Piroxicam - Impurity F or Saccharin N-(2-acetic acid isopropyl ester).

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.

This Piroxicam impurity supports analytical method development and validation (AMV), batch release testing and the impurity sections of 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.
