When sourcing Cholesterol (CAS 57-88-5) for industrial or pharmaceutical applications, understanding the key product specifications is paramount for ensuring optimal performance and quality in your final products. As a reputable cholesterol supplier in China, NINGBO INNO PHARMCHEM CO.,LTD. is committed to transparency and providing detailed information about our offerings. This guide outlines the critical specifications that buyers should look for when purchasing cholesterol.

Purity: This is arguably the most critical specification. For pharmaceutical applications, purity levels of 99.2% or higher are typically required, often with adherence to USP32 or EP6 standards. For cosmetic or feed additives, slightly different purity grades may be acceptable, but consistency is always key. Our cholesterol consistently meets these high purity demands.

Appearance: Cholesterol typically presents as a white or similar sheet crystal. Deviations from this can indicate impurities or improper handling. We ensure our product maintains this characteristic appearance.

Melting Point: A sharp melting point within a specified range (e.g., 147-150℃) is another indicator of purity. Variations can suggest the presence of other sterols or contaminants.

Specific Rotation: This optical property is crucial for chiral molecules like cholesterol and provides another measure of purity and enantiomeric integrity. Our specifications ensure compliance with expected values (e.g., -34º to -38º).

Loss on Drying and Residues: Low loss on drying (e.g., ≤ 0.3%) and minimal residue on ignition (e.g., ≤ 0.1%) are essential to confirm that the product is predominantly cholesterol and free from excessive moisture or inorganic impurities. We diligently monitor these parameters.

For procurement managers and R&D scientists, partnering with a cholesterol manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. that provides detailed specifications and consistent quality is vital. We encourage you to inquire about our cholesterol price and explore our product data to make informed purchasing decisions. Our commitment is to be your trusted source for high-quality cholesterol.
