: Every document must feature a unique Batch or Lot Number that links the reagent back to its original manufacturing record. This is accompanied by the Manufacturing Date and the Expiry or Retest Date to ensure the material is used within its stable shelf-life.

A common mistake is using an outdated COA from a previous batch for a new bottle of the same reagent. Because chemical purity can vary between syntheses, Laboratories that fail to verify the COA update date risk using a reagent that fails to meet their application’s requirements—potentially invalidating months of research or violating an FDA audit trail. : Every document must feature a unique Batch
For high-value or controlled reagents (e.g., precursors for controlled substances), Unichem secures COAs with a one-time code. Solution: The code is usually printed on the bottle’s security label or sent via encrypted email at the time of shipment. Never share this code. Regulatory Peace of Mind A common mistake is
