H Acid, also called 1-Amino-8-Hydroxynaphthalene-3,6-Disulphonic Acid, is a dye intermediate. The free acid is identified by CAS 90-20-0. Commercial sodium-salt grades should be identified separately using the offered material’s documentation.

Quick Answer

H Acid is an industrial intermediate used in azo dye synthesis, including selected reactive, acid and direct dyes. Buyers should confirm the supplied chemical form, assay basis, moisture, insoluble matter and impurity limits. Free-acid and sodium-salt grades require careful specification matching before price comparison or production approval.

Overview of H Acid

H Acid is a naphthalene-based intermediate used to build downstream dye structures. Manufacturers process it with other intermediates to produce the required finished colorant.

Commercial material is commonly offered as a sodium salt. Assay and price comparisons should account for the supplied form and whether strength is calculated on a free-acid or salt basis.

H Acid requires further chemical processing before it becomes a finished dye. Production trials should be completed before changing the approved grade or source.

Applications of H Acid

Reactive Dye Manufacturing

H Acid is used as a coupling component in selected reactive dye manufacturing processes. These downstream dyes are developed for textile dyeing and printing applications.

Manufacturers should assess reaction consistency, yield, color strength and finished-dye performance when comparing sources.

Azo Dye Synthesis

H Acid is an important intermediate for azo dye production. Its role depends on the selected components and production conditions.

Buyers should evaluate assay, dissolution behaviour and process-relevant impurities. Consistent incoming quality helps manufacturers control downstream shade and production results.

Acid and Direct Dye Production

H Acid is used in selected acid and direct dye manufacturing routes. The appropriate grade depends on the intended dye structure and the manufacturer’s approved process.

Finished-dye solubility, shade and application performance should be tested separately. These properties cannot be established from the intermediate’s assay alone.

Black and Other Specialty Dye Manufacturing

H Acid is documented in selected black reactive dye processes and other colorant synthesis routes.

Manufacturers producing consistent shades should compare trial batches for color strength, unwanted shade variation and processing performance before source approval.

Dye Process Development

Dye-development teams use H Acid when evaluating synthesis routes that require this intermediate.

Trials can compare dissolution, conversion, filtration, yield and finished-colorant quality. Results should support the final raw-material specification before recurring purchases.

H Acid Price

The H Acid price depends on chemical form, active content, assay basis, impurity limits, manufacturer, quantity, packing and delivery destination.

For a comparable quotation, provide the required grade, strength calculation basis, approved specification, quantity and delivery location. Confirm whether commercial pricing is based on supplied weight or equivalent active content.

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