A Certificate of Analysis is a formal document issued by a manufacturer's Quality Assurance (QA) or Quality Control (QC) department. For brands under the Unichem umbrella or technical partners handling specialized high-purity analytical reagents, this document confirms that a specific lot or batch matches its stated chemical specifications.
For chemicals that degrade or absorb moisture over time, a recent re-test date is critical, particularly for HPLC solvents, titration standards, or high-purity reagents.
