1,4-Phenylenediamine-2-Sulphonic Acid, also called 2,5-Diaminobenzenesulphonic Acid, PPDSA or PPDOSA, is a dye intermediate identified by CAS 88-45-9. It is used in the manufacture of selected reactive, acid and direct dyes.

Quick Answer

1,4-Phenylenediamine-2-Sulphonic Acid is an industrial intermediate used to manufacture selected reactive, acid, direct and azo dyes. Buyers should confirm CAS 88-45-9, assay, testing method, moisture, insoluble matter and relevant impurity limits. The offered grade should match the approved specification and pass production trials before regular use.

Overview of 1,4-Phenylenediamine-2-Sulphonic Acid

This material is a raw chemical intermediate used in downstream dye synthesis. It requires further processing to produce the finished colorant.

Commercial grades can differ in assay, moisture, appearance and impurity profile. Buyers should compare specifications using the same testing methods and reporting basis.

Manufacturers should assess incoming quality and finished-dye performance before approving a new source.

Applications of 1,4-Phenylenediamine-2-Sulphonic Acid

Reactive Dye Manufacturing

PPDSA is used in selected reactive dye manufacturing processes. Documented downstream products include Reactive Orange 14, Reactive Green 19 and Reactive Blue 2.

Manufacturers should confirm that the offered grade meets their production requirements. Trials should assess reaction consistency, yield, shade and finished-dye strength.

Acid Dye Manufacturing

This intermediate is used in the production of selected acid dyes, including Acid Red 34 and Acid Violet 27.

The finished dye’s suitability depends on its final composition and application properties. Buyers should evaluate shade, solubility and dyeing performance against their approved product standard.

Direct Dye Manufacturing

PPDSA is also used in selected direct dye processes. Documented examples include Direct Red 75, Direct Blue 96 and Direct Green 28.

Consistent raw-material quality supports production control. Manufacturers should compare impurity profiles and evaluate finished-dye results before changing suppliers.

Azo Dye Synthesis

2,5-Diaminobenzenesulphonic Acid is documented in reactive azo dye synthesis as a component used to build the required dye structure.

Its role depends on the production route. Manufacturers should select the material according to the approved process rather than assuming suitability for every azo dye.

Dye Development and Production Trials

Dye-development teams can evaluate PPDSA when developing formulations or synthesis routes that require this intermediate.

Trial batches help compare conversion, filtration behaviour, yield and color consistency. Results should support source approval before recurring bulk purchases.

1,4-Phenylenediamine-2-Sulphonic Acid Price

The 1,4-Phenylenediamine-2-Sulphonic Acid price depends on assay, testing method, impurity limits, manufacturer, quantity, packing, availability and delivery destination.

For an accurate quotation, provide your approved specification, required quantity, packing preference and delivery location. A current COA helps compare the offered grade with your existing material.

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