Purity Certificates
Every batch of every compound we supply is independently tested by accredited third-party laboratories. We provide full transparency with batch-specific Certificates of Analysis (COA) included with every order.
Multi-Stage Testing Process
Before any compound is released, it undergoes a rigorous five-stage analytical protocol to verify identity, purity, and structural integrity.
Raw Material ID
Identity and initial purity screening of incoming materials
HPLC Analysis
High-Performance Liquid Chromatography for quantitative purity
Mass Spectrometry
Molecular weight and structural confirmation via MS
Contamination Screen
Heavy metals (ICP-MS), microbial, and solvent residue testing
COA Generation
Batch-specific Certificate of Analysis issued and verified
What Our COA Reports Include
Each certificate provides a comprehensive analytical profile of the specific batch, including:
| Parameter | Analytical Method | Acceptance Criteria | Status |
|---|---|---|---|
| Compound Identity | Mass Spectrometry (MS) | Matches reference standard | Confirmed |
| Purity | HPLC (UV detection) | ≥ 98.0% | ≥ 99% |
| Molecular Weight | Mass Spectrometry (MS) | Within ± 0.5 Da | Verified |
| Heavy Metals | ICP-MS | < 10 ppm (USP <231>) | Pass |
| Microbiological | USP <61> / <62> | TAMC < 100 CFU/g | Pass |
| Residual Solvents | GC-MS | ICH Q3C Class 2 limits | Pass |
| Moisture Content | Karl Fischer Titration | < 1.0% | Pass |
| Appearance | Visual Inspection | Conforms to specification | Conforms |
