1,3-Phenylenediamine-4-Sulphonic Acid, also called 2,4-Diaminobenzenesulphonic Acid or MPDSA, is a dye intermediate identified by CAS 88-63-1. It is used in selected reactive, acid, direct and mordant dye manufacturing processes.

Quick Answer

1,3-Phenylenediamine-4-Sulphonic Acid is an industrial intermediate used to manufacture selected reactive, acid, direct and mordant dyes. Buyers should confirm CAS 88-63-1, chemical form, assay, test method, moisture, insoluble matter and relevant impurities. Grade approval should include specification comparison and production trials before recurring purchases.

Overview of 1,3-Phenylenediamine-4-Sulphonic Acid

MPDSA is a raw chemical intermediate used in downstream colorant synthesis. It undergoes further processing to produce the required finished dye.

Commercial specifications vary by producer and grade. Buyers should compare assay methods, reporting basis, impurity limits and supplied form when evaluating an alternative source.

The offered grade should match the buyer’s approved specification. Production trials help confirm processing behaviour and finished-dye quality.

Applications of 1,3-Phenylenediamine-4-Sulphonic Acid

Reactive Dye Manufacturing

MPDSA is documented in reactive dye manufacturing routes, including processes for reactive azo dyes. It can participate in the stages used to build the required dye structure.

Manufacturers should assess conversion, yield, shade and finished-dye strength when comparing sources. The required specification depends on the approved production process.

Acid Dye Manufacturing

MPDSA is commercially documented as an intermediate for selected acid dyes.

Buyers should evaluate the resulting dye for shade, solubility and application performance. These properties depend on the complete dye structure and cannot be established from raw-material purity alone.

Direct Dye Manufacturing

Selected direct dye production processes use MPDSA as an intermediate.

Manufacturers should compare process-relevant impurities and confirm consistent trial results before changing suppliers. Incoming quality checks support control of downstream color variation.

Mordant Dye Manufacturing

MPDSA is also documented for selected mordant dye manufacturing applications.

The offered grade should be evaluated against the specific synthesis route. Finished-dye performance must be confirmed through the manufacturer’s application tests.

Dye Development and Production Trials

Dye-development teams can evaluate MPDSA in synthesis routes requiring the 2,4-diaminobenzenesulphonic acid structure.

Trial batches help compare dissolution, reaction consistency, filtration, yield and finished-colorant quality. These results support source approval before larger purchases.

1,3-Phenylenediamine-4-Sulphonic Acid Price

The 1,3-Phenylenediamine-4-Sulphonic Acid price depends on assay, chemical form, impurity limits, manufacturer, quantity, packing, availability and delivery destination.

For a comparable quotation, share the approved specification, assay method, quantity and delivery location. Confirm whether results are reported on an as-supplied or dry basis.

Recurring buyers can provide monthly consumption and purchasing schedules for supply planning.

Why Choose Chemical Bull as an MPDSA Supplier?

Chemical Bull supports industrial sourcing enquiries with specification comparison, technical-document coordination, packing confirmation and shipment planning.
