The expectations listed on a Uni-Chem COA vary wildly depending on the grade of the chemical ordered. Matching the right grade to your application prevents over-spending while ensuring data integrity. Chemical Grade Typical Purity Standard Common Applications Meets American Chemical Society standards High-purity analytical testing, food and drug development. AR (Analytical Reagent) Grade Extremely high purity, detailed impurity tracking Quantitative analysis, chromatography, critical research. Laboratory / CP Grade High purity, but lower than AR grade

The unique identification number assigned to a specific production run. This is the single most important number for tracking quality issues.

Uni-Chem adheres to stringent international regulatory standards. Understanding these requirements helps customers fully appreciate the value of Uni-Chem's COAs. uni-chem chemical reagents certificate of analysis

If a batch number is older or not appearing in the automated online database, contacting the Uni-Chem customer support or technical service team with the product code and lot number will allow them to retrieve the document from their manual archives. Summary of Reagent Grades Typically Found on COAs

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.

Detailed limits and measured values for specific contaminants, such as heavy metals, moisture content, or residue after ignition. 3. Analytical Test Methods Are you setting up a for your lab

Uni-Chem makes it straightforward to obtain a CoA to ensure your laboratory documentation is up-to-date.

A unique identifier for the exact production run, crucial for traceability. Manufacturing Date: When the product was made. Expiry/Retest Date: Defines the shelf-life of the product.

: Many chemical suppliers provide COAs upon request through their quality assurance departments (e.g., info@unichemsolutions.com). This is the single most important number for

: Clearly identifies the reagent.

: The universal chemical registry number for absolute identification. Date & Traceability : Manufacturing Date : When the batch was produced.

The importance of the CoA cannot be overstated, particularly in accredited labs (ISO 17025) or GMP manufacturing environments.

If an experiment fails unexpectedly, the CoA is the first place to look. If the reagent's moisture content is slightly higher than usual—even if still within spec—it might explain why a moisture-sensitive reaction didn't perform as expected. How to Obtain a Uni-Chem CoA
