Magnesium Carbonate, a compound with the CAS number 546-93-0, is a white, crystalline solid that serves a surprisingly wide array of functions across multiple industries. For B2B stakeholders, including purchasing managers, R&D scientists, and product formulators, understanding the core attributes and sourcing channels for this versatile chemical is essential.

Chemically, Magnesium Carbonate (CAS 546-93-0) is the magnesium salt of carbonic acid. It can exist in anhydrous and hydrated forms, though the anhydrous form is commonly used industrially. Its key characteristic of decomposing into magnesium oxide and carbon dioxide upon heating makes it invaluable for producing refractory materials used in high-temperature applications. This conversion is a cornerstone of its utility in the ceramics industry.

Beyond its industrial role, Magnesium Carbonate is well-known for its use as an antacid in pharmaceutical preparations. It effectively neutralizes stomach acid, providing relief from symptoms of heartburn and indigestion. For pharmaceutical manufacturers, sourcing USP or EP grade Magnesium Carbonate ensures compliance with strict quality and safety standards. Additionally, it’s used in some laxative formulations and as a dietary supplement to provide magnesium.

In other sectors, it functions as a drying agent, an anti-caking agent in food products, and an ingredient in cosmetics for absorbing oils and improving texture. Its versatility means that various industries are constantly seeking reliable sources for this compound.

For businesses looking to buy Magnesium Carbonate (CAS 546-93-0), a strategic approach to sourcing is crucial. Partnering with a reputable manufacturer and supplier in China, such as NINGBO INNO PHARMCHEM CO.,LTD., offers significant advantages. This includes competitive pricing for bulk purchases, consistent product quality, and a stable supply chain. By engaging directly with a Chinese manufacturer, you can gain greater control over your procurement process and ensure you are receiving materials that meet your exact specifications, whether for industrial, pharmaceutical, or cosmetic applications.
