Chemical Structure

Chromium CAS 7440-47-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Chromium.

Chromium (CAS 7440-47-3), molecular formula Cr and molecular weight 52.00 g/mol, is a CATO reference standard with documented purity and traceability.

Chromium (Cr) contains an inorganic composition. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), Chromium meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
