7-Dehydrocholesterol
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.

Sourcing 7-Dehydrocholesterol from Wuhan Yuan Cheng GongChuang Technology Co.Ltd - China Import Guide
Before placing an order, verify the supplier’s compliance with Good Manufacturing Practices (GMP) or ISO 9001 standards, as these are critical for pharmaceutical-grade materials. Request recent CoA reports for the specific batch you intend to purchase to confirm purity, impurity profiles, and microbial limits. For cosmetic applications, ensure the material meets regional regulatory requirements such as EU Cosmetic Regulation 1223/2009 or FDA guidelines.
Confirm logistics details, including cold-chain capabilities, as 7-Dehydrocholesterol requires temperature-controlled transport to prevent degradation. Discuss Incoterms such as FOB Wuhan or CIF to your port, and clarify whether the supplier can provide nitrogen-flushed packaging or other stability-enhancing measures. Payment terms should be negotiated based on your risk assessment, with options like T/T or L/C commonly used for first-time transactions.
Quality checks should include visual inspection for color and crystalline structure, as well as analytical testing for purity and impurity content upon receipt. For pharmaceutical use, consider third-party testing to validate the CoA provided by the supplier. Ensure the shipment includes all required documentation, such as the CoA, MSDS, and any regulatory certifications needed for customs clearance in your destination country.
