Uni-chem Chemical Reagents Certificate Of Analysis May 2026

Among global manufacturers, has established a reputation for rigorous quality assurance. Their Chemical Reagents Certificate of Analysis is not merely a piece of paper; it is a legally binding fingerprint of the product’s identity, purity, and physical characteristics.

When they requested the CoA from the discount supplier, they received a generic “Certificate of Suitability” with no batch number. They could not trace the impurity. uni-chem chemical reagents certificate of analysis

In this article, we will dissect the Uni-Chem CoA, explain why it matters for compliance (ISO, GMP, USP), and teach you how to read every line to ensure your research stands on solid ground. Before diving into the specifics of Uni-Chem’s documentation, we must understand the function of a CoA. Among global manufacturers, has established a reputation for

| Test | Specification | Result (Example) | | :--- | :--- | :--- | | | Clear, colorless liquid | Conforms | | Assay (GC) | ≥ 99.9 % | 99.95 % | | Water Content (KF) | ≤ 0.02 % | 0.008 % | | Residue after Evaporation | ≤ 0.0005 % | 0.0001 % | | UV Absorbance (200nm) | ≤ 0.05 AU | 0.03 AU | They could not trace the impurity

Whether you are running a sensitive LC-MS/MS assay, synthesizing a new pharmaceutical intermediate, or teaching a university organic chemistry lab, always demand the CoA. And when you see the Uni-Chem logo on that certificate, you know you have the data to trust your next discovery.

A Certificate of Analysis is a document issued by the quality assurance (QA) department of a chemical manufacturer. It certifies that a specific batch (lot) of a chemical reagent has been tested and meets predetermined specifications.
