1-(2,5-Dichloro-4-Sulfophenyl)-3-Methyl-5-Pyrazolone Supplier & Distributor In India

Chemical Bull is a 1-(2,5-Dichloro-4-Sulfophenyl)-3-Methyl-5-Pyrazolone supplier, distributor, and exporter in India, supporting sourcing enquiries from dye manufacturers, dye intermediate producers, specialty chemical companies, synthesis laboratories, distributors, wholesalers, and global B2B buyers.

1-(2,5-Dichloro-4-Sulfophenyl)-3-Methyl-5-Pyrazolone, CAS 84-57-1, is also known as Dichlorosulfophenyl Methyl Pyrazolone or DCSPMP. It is a chlorinated, sulfonated pyrazolone intermediate used as a coupling component in selected azo dye synthesis routes.

Overview of Dichlorosulfophenyl Methyl Pyrazolone

The compound contains a methyl-substituted pyrazolone ring attached to a phenyl group bearing two chlorine substituents and a sulfonic acid group. The substitution pattern is important for chemical identification and manufacturing approval.

The acid form has the molecular formula C10H8Cl2N2O4S and a molecular weight of approximately 323.15 g/mol. The monohydrate has the formula C10H8Cl2N2O4S·H2O and a molecular weight of approximately 341.17 g/mol. Confirm the supplied hydration state and assay basis before ordering.

Commercial grades differ in assay, moisture, inorganic salt content, physical form, and process-related impurities. Review the offered specification and batch COA against your approved raw-material requirements.

This sulfonated product should not be confused with 1-(2,5-Dichlorophenyl)-3-Methyl-5-Pyrazolone, which lacks the sulfonic acid group. Each material requires separate process approval.

Applications of 1-(2,5-Dichloro-4-Sulfophenyl)-3-Methyl-5-Pyrazolone

Azo Dye Manufacturing

The compound serves as a coupling component in suitable azo dye synthesis routes. Manufacturers should evaluate compatibility with the selected diazo component and the required finished-dye specification.

Selected Reactive Dye Synthesis

Dichlorosulfophenyl Methyl Pyrazolone is documented among coupling components for selected reactive dye synthesis processes. Suitability depends on the target dye structure and reactive-group chemistry.

Textile Colorant Development

Colorant development teams can evaluate this intermediate in dye synthesis projects for textile colouring and printing. Shade, fixation, solubility, and fastness must be established for the finished dye through application testing.

Organic Synthesis & Process Research

Industrial laboratories can use the material in route-specific synthesis, coupling studies, and process development. Assay, hydration, and impurity carryover should be considered when assessing reaction behaviour and scale-up suitability.
