Thermo Scientific™ Magnesium Carbonate Basic, Heavy is an extra pure grade of basic magnesium carbonate designed for laboratory, analytical, and industrial applications requiring high purity. This compound features a magnesium oxide (MgO) content of 40 to 45% and is characterized by high bulk density and excellent whiteness, making it ideal for a wide range of chemical and pharmaceutical uses.
This basic form of magnesium carbonate includes both hydroxide and carbonate groups and conforms to strict quality specifications, including low levels of soluble salts, calcium oxide, and acid-insoluble substances. It is provided as a white to almost white fine powder, ensuring ease of use in dry blending, buffer formulations, and other solid-phase preparations.
Key Features & Benefits
- High MgO Content (40–45%) for effective buffering and neutralizing applications.
- Low Soluble Salt Content (≤1.0%) ensures minimal ionic interference in sensitive reactions.
- Minimal Impurities: Low levels of CaO (≤0.6%) and acid-insoluble residues (≤0.05%).
- Stable White Powder form, ideal for precise formulation and blending.
- Extra Pure Grade suitable for analytical procedures and pharmaceutical intermediates.
- Packaged in Secure Plastic Bottles or Drums to maintain stability and prevent contamination.
