Description

Magnesium Sulfate Trihydrate is a high-purity, crystalline inorganic salt essential for numerous industrial and pharmaceutical processes. Its primary value lies in its reliable source of bioavailable magnesium and sulfate ions, which are critical for chemical synthesis, nutrient supplementation, and water treatment. This product is particularly vital for manufacturers in the pharmaceutical, agriculture, food & beverage, and chemical industries seeking a consistent and high-quality raw material.

Application

• Pharmaceutical Manufacturing: Used as an active pharmaceutical ingredient (API) in magnesium supplements, laxatives, and electrolyte replenishers. Also serves as a reagent in various synthesis processes.
• Agriculture & Horticulture: A key component in magnesium-deficient soil fertilizers and foliar sprays to correct nutrient imbalances and promote plant health and chlorophyll production.
• Food & Beverage Industry: Employed as a firming agent, nutrient supplement, and brewing salt in beer production, compliant with food-grade specifications (e.g., FCC).
• Industrial Chemical Synthesis: Acts as a precursor or catalyst in the production of other magnesium compounds, dyes, and specialty chemicals.
• Water Treatment: Utilized in wastewater treatment processes to precipitate contaminants and adjust water chemistry.
• Laboratory & Research: Serves as a standard reagent and culture medium component in microbiological and biochemical applications.

Quality Control

Our Magnesium Sulfate Trihydrate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. We can supply material compliant with various pharmacopeial standards (USP/EP/BP) or food-grade (FCC) requirements upon request. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistent quality.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are kept sealed to prevent absorption of atmospheric moisture and caking.
