From time to time, the Compendial Lots that these Secondary Standards are made traceable to change. This necessitates a requalification of the Secondary Standard Lot against the current lot of Compendial reference standards or substances and a subsequent update to the Certificate of Analysis. The Secondary Standard portfolio is being updated continually with new products and replacement batches of existing products. The latest Secondary Standard information can be found below. For more details, visit Secondary Standards for Pharmaceutical Quality Control.

Updated COAs can be found by following the material link in the table and entering the batch in the appropriate location.
