Overview

N-butan-2-ylidenehydroxylamine (CAS 96-29-7) is an oxime compound with significant industrial applications and notable hazard classifications requiring careful handling protocols. This organic compound, with the molecular formula C4H9NO and a molecular weight of 87.12 g/mol, belongs to the oxime family of chemicals characterized by the presence of a C=N-OH functional group. The substance is officially registered under EC number 202-496-6 and carries multiple hazard classifications that underscore its potential risks in industrial environments. The compound presents serious safety considerations, classified as a Category 1B carcinogen alongside acute toxicity ratings of Category 3 and 4. Additional hazard classifications include specific target organ toxicity for both single and repeated exposure (STOT SE 1, STOT SE 3, and STOT RE 2), eye damage Category 1, and skin irritation Category 2. These classifications necessitate the "Danger" signal word and require appropriate GHS pictograms including GHS08 (health hazard), GHS06 (toxic), and GHS05 (corrosive). For transportation purposes, the substance falls under ADR Class 3, indicating its flammable nature. In industrial applications, N-butan-2-ylidenehydroxylamine serves primarily as an intermediate in organic synthesis processes and finds use in pharmaceutical manufacturing and specialty chemical production. Its oxime structure makes it valuable in certain catalytic processes, distinguishing it from related compounds such as prop-2-enenitrile, which serves different synthetic pathways. Given its hazardous nature, proper handling protocols, adequate ventilation systems, and appropriate personal protective equipment are essential when working with this compound. OYSI maintains availability of N-butan-2-ylidenehydroxylamine with full regulatory documentation and safety data sheets for qualified industrial customers.
