1-3-Chloro Phenyl-3-Methyl-5-Pyrazolone Supplier & Distributor In India

Chemical Bull is a 1-3-Chloro Phenyl-3-Methyl-5-Pyrazolone supplier, distributor, and exporter in India, supporting sourcing enquiries from dye manufacturers, colorant producers, specialty chemical companies, synthesis laboratories, distributors, wholesalers, and global B2B buyers.

1-3-Chloro Phenyl-3-Methyl-5-Pyrazolone, CAS 90-31-3, is also known as 1-(3-Chlorophenyl)-3-Methyl-5-Pyrazolone or m-Chloropyrazolone. It is a substituted pyrazolone intermediate used in selected dye manufacturing and organic synthesis processes.

Overview of 1-3-Chloro Phenyl-3-Methyl-5-Pyrazolone

The compound has the molecular formula C10H9ClN2O and a molecular weight of approximately 208.65 g/mol. Its structure contains a methyl-substituted pyrazolone ring attached to a phenyl group bearing chlorine at the meta position.

The material is a solid, with reference grades described as white to light-yellow powder or crystals. Appearance, assay, and physical specifications should be confirmed for the offered commercial grade.

The meta-chloro substitution is important for product identification. This material should not be confused with the corresponding ortho-chloro or para-chloro isomers, which require separate approval for the intended manufacturing route.

Buyers should review identity, assay and test method, moisture, residual starting materials, positional-isomer impurities, and process-specific quality limits. Confirm storage and air-exposure requirements before procurement.

Applications of 1-3-Chloro Phenyl-3-Methyl-5-Pyrazolone

Dye Intermediate Manufacturing

1-3-Chloro Phenyl-3-Methyl-5-Pyrazolone is used as an intermediate in selected dye manufacturing routes. Grade selection depends on the target dye structure and approved raw-material specification.

Azo Dye Coupling

The substituted pyrazolone can serve as a coupling component in suitable azo dye synthesis processes. Manufacturers should assess compatibility with the chosen diazo component and the required finished-product properties.

Specialty Organic Synthesis

Specialty chemical developers use the compound as a heterocyclic building block in route-specific organic synthesis. Its chlorophenyl and pyrazolone structure provides a defined starting point for selected chemical transformations.

Colorant Research & Process Development

Industrial laboratories can evaluate the material in colorant development, coupling studies, and process optimisation. Reaction behaviour, impurity carryover, and finished-colorant performance should be established through application testing.
