Zinc Sulphate CAS#7733-02-0
Basic Information
Zinc sulfate is a white, water-soluble crystalline zinc salt, commonly supplied as the heptahydrate. The hydrate loses crystal water progressively on heating, giving predictable behavior during drying and thermal processing. It is used as a mordant in dyeing and as a zinc source in fungal culture media and protein-expression systems. Analytical laboratories also use it for blood-sample deproteinization in glucose-assay workflows.

High-Purity Water-Soluble Crystals：White crystalline zinc sulfate with excellent solubility, commonly supplied as stable heptahydrate (ZnSO₄·7H₂O).
Thermal Dehydration Stability：Gradually loses water above 30 °C and converts to anhydrous form at high temperature, offering predictable behavior during processing.
Traditional & Industrial Applications：Formerly known as white vitriol, widely used as a mordant in dyeing and as a styptic for bleeding control.
Reliable Chemical Performance：Produced from zinc sulfide ore with consistent quality for laboratory, pharmaceutical, and industrial uses.
Products Description of Zinc Sulphate CAS#7733-02-0
Zinc sulphate (white vitriol) is a white crystalline water-soluble salt, typically supplied as the heptahydrate (density ~1.9). It dehydrates sequentially with heating and decomposes above 500 °C. Used as a dyeing mordant and styptic.
Product Applications of Zinc Sulphate CAS#7733-02-0
Zinc sulphate is used in fungal growth culture media, as a zinc supplement for zinc-containing protein expression (with IPTG), and for blood sample deproteinization (with barium hydroxide) in Somogyi–Nelson glucose assays.

Caustic Soda
NaOH
Flakes; Granules; Beads; Lumps
Sodium hydroxide, commonly known as caustic soda, is an inorganic compound with the chemical formula NaOH. It is a white, hygroscopic solid that dissolves readily in water with the release of heat, forming a strongly alkaline and corrosive solution. It is used for acid neutralization, saponification, grease removal and pH adjustment, with applications in pulp and paper production, textile processing, wastewater treatment, chemical manufacturing and petroleum refining.![Citric Acid Monohydrate]( "Citric Acid Monohydrate")
Citric Acid MonohydrateCitric Acid Monohydrate
Crystals; Granules; Powder
Citric acid monohydrate is an odorless crystalline organic acid containing water of crystallization. Readily soluble in water and soluble in ethanol, it provides acidity and metal-ion chelation in formulations. It is used for flavor adjustment in foods and beverages, as a cleaning ingredient in detergents, and in cosmetic and chemical processing applications.![Polyvinyl Chloride Paste Resin]( "Polyvinyl Chloride Paste Resin")
Polyvinyl Chloride Paste ResinPolyvinyl Chloride Paste Resin
Dispersed PVC Resin
White fine powder
Polyvinyl chloride paste resin, also called dispersed PVC resin, is a fine white powder designed to disperse in plasticizers. Its small primary particles produce homogeneous plastisols for coating, impregnation, and casting. Applications include artificial leather, wallpaper, vinyl toys, gloves, automotive interiors, adhesives, and coatings requiring a workable paste-based processing route.![Xylene]( "Xylene")
XyleneXylene
Colorless liquid
Xylene is a clear, colorless aromatic hydrocarbon liquid with a characteristic odor. Insoluble in water but compatible with many organic solvents, it dissolves resins, oils, and rubber while providing useful evaporation behavior. It serves as a coating thinner, ink solvent, resin-processing medium, adhesive ingredient, and industrial cleaning solvent.![Ethyl acetate]( "Ethyl acetate")
Ethyl acetateEthyl acetate
Colorless liquid
Ethyl acetate is a clear, colorless ester solvent distinguished by its fruity odor and rapid evaporation. It mixes with ethanol, ether, and other organic solvents while having limited water solubility. Its solvency for oils, resins, and organic materials supports coatings, printing inks, adhesives, extraction, leather processing, and industrial cleaning.![Sodium Lauryl Ether Sulfate(SLES)]( "Sodium Lauryl Ether Sulfate(SLES)")
