CAS Number: 7446-19-7
Zinc Sulphate Monohydrate is a water-soluble zinc salt supplied as a white to off-white crystalline powder. It has the molecular formula ZnSO₄·H₂O, CAS number 7446-19-7 and molecular weight of approximately 179.47 g/mol. The product is available in different commercial grades containing approximately 27% to 33% elemental zinc expressed as Zn. The stated percentages refer to elemental zinc content and should not be interpreted as Zinc Sulphate purity. Zinc Sulphate Monohydrate is used as a source of zinc and sulphur in agricultural micronutrient formulations, fertilizer manufacturing, fertilizer blending, crop-nutrition products, chemical processing, textile applications and other industrial formulations. The 33% Zn grade may be supplied against applicable Indian fertilizer specifications when the complete chemical, contaminant and quality requirements are confirmed through current regulatory documentation and batch-specific testing. A 27% Zn grade should be treated as a separate commercial specification and should not automatically be represented as conforming to the notified 33% monohydrate fertilizer standard. Mangalam Acid & Chemicals supplies Zinc Sulphate Monohydrate from Vapi, Gujarat, India, in different zinc-content grades for bulk agricultural-formulation and industrial requirements. Buyers should specify the required 27% or 33% grade and request the latest Certificate of Analysis, Safety Data Sheet and applicable compliance documentation before use.
