5-Chloro-2-Nitroaniline (CNA) is a high-purity aromatic intermediate for advanced chemical synthesis.
5-Chloro-2-Nitroaniline (CNA) is a key nitroaniline derivative widely used as an intermediate in the manufacture of APIs, agrochemicals, pigments and other specialty chemicals. Its chloro and nitro functional groups make it an excellent building block for further substitution, reduction and coupling reactions, supporting a broad range of downstream products.
CNA is supplied as a free-flowing yellow crystalline powder with high assay by HPLC and very low levels of controlled impurities. Strict specifications for moisture, individual impurities (such as 2,4-DCNB, diamine and isomeric impurities) and total impurity content ensure reliable performance in sensitive multi-step syntheses.
Produced under controlled conditions and supported with a detailed Certificate of Analysis for every batch, our CNA offers consistent quality, good solubility in methanol and excellent thermal stability within its defined melting range. This makes it a dependable choice for process development as well as large-scale commercial production.
