Product Description
Magnesium Sulphate Monohydrate (Molecular Formula: MgSO₄·H₂O, CAS Number: 14168-73-1, HS Code: 28332100, Density: 2.66 g/cm³) dissolves readily in water, is micro-soluble in alcohol, and is insoluble in acetone. Combining the powerful physiological benefits of standard kieserite with customizable color finishes, it provides high aesthetic appeal and easy brand or batch identification for bulk blending. Because magnesium serves as a core structural element of chlorophyll, this colored granular product is globally recognized and widely applied as a high-performance agricultural fertilizer and soil conditioner.
