Does CAS 97-05-2 identify the same form as 5-Sulfosalicylic Acid Dihydrate CAS 5965-83-3?

No. CAS 97-05-2 identifies 5-sulfosalicylic acid on the anhydrous substance basis, while CAS 5965-83-3 is used for the dihydrate. The hydrate changes formula weight, water content and assay basis. State the required CAS number, free-acid or dihydrate form and assay basis.

What is Sulfosalicylic Acid used for?

Sulfosalicylic acid is used as a chelating and analytical reagent in selected technical and laboratory processes. Application suitability depends on the hydration form, assay and impurity profile, so the intended technical use should be stated and matched to the current product specification.

Which specifications should be agreed for Sulfosalicylic Acid?

Agree assay on the stated hydration basis, water or loss on drying, appearance and colour, insoluble matter, free sulfate, chloride, iron and other metal limits with the methods. Analytical, chelating and process grades may use different impurity profiles.

What physical form and packaging should be confirmed?

Confirm whether anhydrous material or a specified hydrate is required, together with the supplied solid form and any colour or particle requirements. Select packaging suitable for the offered material and destination, and state the hydration and moisture data needed for grade acceptance.

What information should an RFQ include for Sulfosalicylic Acid?

State whether anhydrous material or a specified hydrate is required, together with assay, impurities, quantity, packaging and intended technical use. Request the current product specification, and review handling, storage and local regulatory suitability before ordering.

Sulfosalicylic Acid CAS 97-05-2

Sulfosalicylic Acid, CAS 97-05-2, is also known as 5-sulfosalicylic acid or 2-hydroxy-5-sulfobenzoic acid. It is a chelating and analytical reagent used in selected technical and laboratory processes.
