For businesses operating within the pharmaceutical, nutraceutical, and food industries, sourcing high-quality raw materials is paramount. Magnesium Citrate Anhydrous, a compound with the CAS number 144-23-0, stands out due to its dual role as an effective saline laxative and a bioavailable magnesium supplement. This guide is crafted to assist procurement managers and R&D scientists in understanding what to look for when purchasing this critical ingredient, emphasizing the benefits of partnering with reputable manufacturers and suppliers.

Understanding Magnesium Citrate Anhydrous (CAS 144-23-0)
Magnesium Citrate Anhydrous is a white powder that serves as a crucial Active Pharmaceutical Ingredient (API). Its chemical formula, C6H6MgO7, and molecular weight of 214.41 underscore its specific composition. The key applications of this compound revolve around its osmotic laxative properties, drawing water into the intestines to facilitate bowel movements, and its role as a highly absorbable source of magnesium, essential for numerous bodily functions including muscle and nerve function, blood glucose control, and blood pressure regulation.

Key Quality Parameters for Procurement
When you decide to buy Magnesium Citrate Anhydrous, several quality specifications should be non-negotiable. A reputable manufacturer will provide documentation detailing:

  • Appearance: Should be a white powder.
  • Magnesium Content: Typically within a range like 14.5-16.4%.
  • Loss on Drying: Keeping moisture low, e.g., ≤2.0%, is crucial for stability.
  • Impurity Limits: Strict controls on chloride (≤0.05%), sulfate (≤0.2%), arsenic (≤3ppm), and heavy metals (≤50ppm) are vital for pharmaceutical applications.
  • Microbiological Purity: Low total aerobic count (≤1000 Cfu/g) and absence of specific pathogens like E. coli and Salmonella are critical.

Ensuring these parameters are met is key to selecting a reliable Magnesium Citrate Anhydrous supplier.

Applications Driving Demand
The demand for Magnesium Citrate Anhydrous is driven by its versatility:

  • Pharmaceuticals: As a laxative agent and an active ingredient in treatments for magnesium deficiency. Purchasing pharmaceutical grade API ensures efficacy and safety.
  • Nutritional Supplements: Incorporated into dietary supplements for bone health, muscle function, and overall well-being. Formulators often seek suppliers who can provide this in bulk quantities.
  • Food Fortification: Used to enrich food products with essential magnesium, enhancing their nutritional profile.

When looking to purchase, consider suppliers who can cater to specific application needs.

Choosing Your Manufacturer and Supplier in China
Selecting a Magnesium Citrate Anhydrous manufacturer in China requires due diligence. Look for companies with robust quality management systems, certifications, and a proven track record. A good supplier will offer competitive pricing, reliable lead times, and excellent customer support, including readily available samples for testing. Proximity in sourcing can also lead to cost efficiencies and streamlined logistics when you buy.
