High-Purity 7-Dehydrocholesterol Powder | Vitamin D3 Precursor for Pharmaceutical & Research Applications | GMP-Certified Supply
Xi'an Jiayuan Bio-tech Co., Ltd., established in 2002, registered capital RMB 30 million, supplies pharmaceutical quality 7-Dehydrocholesterol Powder with purity ≥98%, produced in ISO9001 and GMP certified manufacturing lines. Vitamin D3 is produced from this cholesterol derivative, which is widely employed in pharmaceuticals, lab research, and functional supplement development. We have two specialised production factories with 20+ years of industry experience, quality control, scalability from 1KG MOQ, and global logistics via DHL, FedEx, and particular European and American shipping networks.

What Is 7-Dehydrocholesterol Powder?
After being exposed to UVB radiation, a white crystalline substance (CAS No.: 434-16-2) is produced. This material is found in skin tissue naturally and serves as the building block for cholecalciferol, often known as vitamin D3. This sterol has a molecular weight of 384.64 and a chemical formula of C27H44O. Photochemical conversion to pre-Vitamin D3 occurs in living organisms.
It is used as a base material to synthesise analogues of Vitamin D3 in pharmaceutical research. It is used by research labs for the study of membrane fluidity and steroid production. Assay purity of our powder is ≥98% and it has a 2 year shelf-life when stored under regulated circumstances.

Application Fields
Pharmaceutical Manufacturing: Employed in the regulated synthesis of Vitamin D3 derivatives for treatments of osteoporosis and calcium absorption therapies. The powder is suitable in multi-step chemical processes which need exact stoichiometric ratios.
Laboratory Research: It is the reference standard in the study of lipid metabolism, membrane biophysics, and steroid production. The high purity allows for reliable HPLC and mass spectrometry analysis.
Supplement Development: Serves as a raw material for developing innovative Vitamin D delivery methods, including liposomal formulations and nanoparticle encapsulations, to tackle bioavailability issues in functional meals.
Quality assurance
We have a three-level validation procedure for our quality assurance:
Material Screening: Molecular identity before processing verified spectroscopically (UV, IR)
In-Process Monitoring: Real-time HPLC analysis during crystallisation guaranties purity thresholds
Testing of the finished product: Third-party COA includes microbiological limitations (total plate count <1000 CFU/g), heavy metals (<10 ppm), residual solvent analysis
All batches are tested for stability as per ICH requirements. In storage under a blanket of nitrogen, the moisture level is kept below 0.5%.
Certificates
Our facilities are certified to ISO9001:2015, FSSC22000, HALAL, KOSHER and HACCP. We keep comprehensive traceability paperwork in compliance with FDA 21 CFR Part 11. Our GMP workshop settings and cross-contamination avoidance measures are validated by SGS audit reports.
