Magnesium Chloride Hexahydrate FCC, USP GRADE

Product Overview

Magnesium Chloride Hexahydrate FCC, USP GRADE (Magnesium Chloride Hexahydrate; Magnesium Chloride 6-Hydrate) is a highly soluble inorganic salt with the chemical formula MgCl₂·6H₂O. This USP/GMP-grade hydrate is expected to meet stringent pharmaceutical and food-grade specifications, delivering consistent assay results and low impurity levels suitable for legally compliant applications. The material exhibits hygroscopic behavior, readily dissolving in water to form moderately concentrated magnesium chloride solutions that support a range of processing and formulation needs. Typical assay acceptance is 99.5% with an allowable range of 99–100.5% as determined by standardized titration methods, ensuring reliable lot-to-lot content for regulated industries. Its physical form is crystalline, and the product is specified with tight control of residuals, color, and contaminant ions per USP/ACS monographs. This product is storage-stable under proper conditions and designed to support critical uses in pharmaceutical manufacturing, electrolyte formulations, and moisture management in process streams.

Second paragraph: The hexahydrate form offers robust solubility and predictable hydration behavior, making it suitable for de-icing, dust control, and specialty applications where precise magnesium ion delivery is required. The material complies with USP/ACS guidelines and is qualified for inclusion in GMP environments, with COA parameters reflecting controlled heavy metals, halides, and anion profiles. Typical applications include pharmaceutical excipient use, electrolyte preparation for batteries, and moisture-retaining formulations in pharmaceutical and food processing contexts. This product is aligned with industry standards, including ASTM/USP references, to support rigorous quality control and regulatory documentation.

Safety Precautions

First safety paragraph: Handle and store magnesium chloride hexahydrate in a cool, dry place in tightly closed containers to prevent moisture uptake. Use HDPE or glass containers and work in a well-ventilated area to minimize dust exposure. Wear appropriate PPE, including chemical-resistant gloves, safety goggles, and protective clothing to avoid skin and eye contact. Follow standard operating procedures (SOPs) aligned with OSHA and your site’s risk assessment; ensure MSDS/SDS is accessible for batch-specific details and emergency contacts.

Second safety paragraph: Avoid contact with strong acids, which may release HCl and alter hydration state. Exposure to dust may cause irritation; in case of contact, rinse eyes thoroughly with water for several minutes and seek medical attention if irritation persists. Inhalation of dust should be mitigated with adequate ventilation; if inhaled, move to fresh air and seek medical advice if symptoms develop. In the event of ingestion, rinse mouth and do not induce vomiting unless advised by medical personnel. Follow UN transport guidelines (UN 1748, Magnesium Chloride, Class 8, PG III) for shipping and handle per SDS instructions and local regulations.
