Guide: Unichem Chemical Reagents Certificate of Analysis (CoA) Management

1. Introduction

A Certificate of Analysis (CoA) is a critical document in laboratory and industrial settings. It attests that a specific batch of chemical reagents meets the required specifications and quality standards.

4. Audit Trail Integrity

Auditors (FDA, ISO 17025) explicitly ask: “How do you ensure you are using the current version of the supplier’s COA?” If your answer is “We use the one that came in the box,” you risk a 483 observation. The correct answer: “We check the Unichem portal for the latest upd before each use.” unichem chemical reagents certificate of analysis upd

Scenario C: Correction of Errors

Rarely, a clerical error may occur on an issued CoA. Product Name & Catalog Number: The exact identity

When requesting a COA, ensure you have the following details ready: Product Name : The full name and grade of the reagent. Catalog/Item Number : The unique identifier for the chemical. Lot/Batch Number Scenario B: Re-Tested Products (Extension of Shelf Life)

Unichem typically provides CoAs through two channels:

Whether you are performing a routine quality control check or preparing for a rigorous audit, knowing how to retrieve and verify an updated COA is essential. What is a Unichem Certificate of Analysis?

Key Data Fields on a Unichem COA:

  • Product Name & Catalog Number: The exact identity of the reagent (e.g., Unichem HPLC Grade Methanol, UNI-ME-005).
  • Lot/Batch Number: The unique identifier for the specific manufacturing run. This is the most critical link between the physical bottle and the document.
  • Manufacturing & Expiry Dates: Defines the window of validated stability.
  • Test Specifications: Listed parameters such as Assay (purity %), Identity (IR/NMR confirmation), Residue on Ignition, Water Content (KFT), and Heavy Metals.
  • Observed Results: The actual measured values for the specific batch.
  • Method References: USP, EP, JP, or ASTM standards used for testing.
  • Authorized Signatures: Digital or physical stamps from Unichem’s QC manager.

Scenario B: Re-Tested Products (Extension of Shelf Life)

Some reagents have a defined shelf life. If a reagent approaches its expiry date but is chemically stable, Unichem (or an internal QC lab) may re-test it.
