NCSS has expanded its list of approved reference materials.

A new type of approved reference material (ARM) produced by the National Center of Standard Samples has passed metrological expertise and was approved by order of the Federal Agency for Technical Regulation and Metrology (Rosstandart) (Order No. 1788 dated August 26, 2025).

The registry has been expanded with a reference material for the composition of zoledronic acid monohydrate.

The company reported that this is the first reference material developed this year using its own funds, rather than under a federal program.

Thus, as of September 2, 2025, the registry includes 250 different types of ARMs produced by NCSS.

Reference materials are used to control the quality of investigated medicinal products and ensure drug safety within the country.
