What should laboratories review when sourcing research compounds?

Key procurement checks

When sourcing laboratory research compounds, laboratories should evaluate both the analytical documentation and the supplier’s quality controls before purchase. The goal is to confirm that the material is suitable for research use only and is not intended for human consumption.

• Identity evidence: Confirm that the compound is supported by appropriate identity testing, such as mass spectrometry or other validated analytical methods.
• Purity data: Review HPLC or comparable chromatographic results to understand the reported purity and any stated impurities.
• COA consistency: Check that the certificate of analysis matches the lot number, product name, and test methods.
• Traceability: Look for batch or lot information that links the material to manufacturing and testing records.
• Handling information: Confirm storage conditions, packaging integrity, and shipment documentation.

For laboratory purchasers, the most important step is to verify that the supplier provides transparent, batch-specific documentation that supports reproducible research and internal quality review.
