从China供应商批发进口7-Dehydrocholesterol — FOB条款

7-Dehydrocholesterol is a sterol compound and a natural provitamin D3 precursor, supplied as a high-purity powder for pharmaceutical and nutraceutical use. This biochemical reagent functions as a key intermediate in vitamin D3 synthesis and is also incorporated into cosmetic dermatology formulations for its skin-active properties. The product is traded in bulk under cold-chain conditions to preserve stability, with a Certificate of Analysis provided for each batch.

The material is a white to off-white crystalline powder, soluble in organic solvents such as ethanol and chloroform but insoluble in water. Typical industry grades for pharmaceutical use exceed 98% purity, with strict limits on heavy metals, residual solvents, and microbial contamination as per USP or EP standards. The compound is sensitive to light and oxidation, requiring inert atmosphere packaging or nitrogen flushing for long-term storage.

Primary buyers include vitamin D3 manufacturers, skincare formulators, and nutraceutical producers sourcing export-grade material for large-scale production. The product is commonly shipped in 25 kg fiber drums with inner polyethylene liners, and cold-chain logistics are advised for regions with ambient temperatures above 25°C. Buyers should confirm packaging specifications and stability data for their intended application, as handling requirements may vary by downstream process.
