About Isonitrosoacetone

Listed under CAS 306-44-5, Isonitrosoacetone is a nitrosamine impurity standard available from Vaqora Chemicals. With the molecular formula C3H5NO2, it has a molar mass of 87.08 g/mol. The IUPAC name is (1E)-1-hydroxyiminopropan-2-one. Alternative names: Monoisonitrosoacetone and Propanone 1-oxime.

The product is provided as a solid. Reference materials should be stored sealed and away from light and moisture, as specified on the accompanying COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this nitrosamine standard to develop and validate highly sensitive LC-MS/MS methods, to confirm limits of detection and to document nitrosamine risk assessments in regulatory submissions. 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.
