4-Chloro-2-nitrophenol

CAS No 89-64-5

4-Chloro-2-nitrophenol

Category

Dye and Pigment Intermediates

Sub-Category

Nitrophenols

Description : 4-Chloro-2-nitrophenol operates as a bifunctional intermediate in the synthesis of agrochemical actives, specialty dyes, and pharmaceutical precursors like 2-amino-4-chlorophenol derivatives. Manufacturing requires controlled nitration of p-chlorophenol, where maintaining accurate temperature profiles prevents hazardous side reactions and ensures low levels of isomeric nitro impurities. Sourcing demand is sustained by global crop protection chemical manufacturers and custom synthesis CDMOs operating under rigorous regulatory compliance. As globally established 4-Chloro-2-nitrophenol supplier with 4-Chloro-2-nitrophenol 98%, scimplify ensures dependable supply, consistent quality, and complete regulatory documentation, including 4-Chloro-2-nitrophenol CoA and 4-Chloro-2-nitrophenol TDS across all grades. Beyond supply, we support partners through the entire product sourcing framework from scouting, process development, pilot-to-commercial manufacturing of 4-Chloro-2-nitrophenol. We support procurement with region specific compliances, GMP quality assurance with 4-Chloro-2-nitrophenol sds, regulatory documentation, global supply chain capabilities and logistics coordination
