About Framycetin sulfate

Framycetin sulfate is an impurity of Neomycin carrying the CAS registry number 28002-70-2. Formula C23H48N6O17S, molecular weight 712.7 g/mol. It is also known as Neomycin B Sulphate or Neomycin B Sulfate.

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. It carries the GHS signal word “Danger” with 5 hazard statements. Review the Safety Data Sheet before use.

As a characterised impurity of Neomycin, it is used for analytical method development, method validation (AMV) and routine quality-control testing, and it supports ANDA and DMF regulatory filings. 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.
