About N-Formyl-L-leucine

N-Formyl-L-leucine (CAS 6113-61-7) is an impurity of Orlistat offered by Vaqora Chemicals. Formula C7H13NO3, molecular weight 159.18 g/mol. Systematically, it is named (2S)-2-formamido-4-methylpentanoic acid. Alternative names: N-Formylleucine and L-Leucine, N-formyl-.

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 Orlistat impurity supports analytical method development and validation (AMV), batch release testing and the impurity sections of ANDA and DMF filings. It is used across 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.
