Para-Nitroaniline (p-NA)
CAS Number: 100-01-6
Para-nitroaniline (p-NA) is a key diazo component in the manufacture of azo dyes, particularly fast yellow and orange dyes used in textiles, leather, and paper. It undergoes diazotization at low temperature and couples with naphthalenic and phenolic components to produce brilliant shades. Chemzip offers technical and refined grades to meet various manufacturing requirements.
