Chemical Structure
Description
Cu (CAS 7440-50-8), molecular formula Cu and molecular weight 63.55 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an inorganic composition, Cu is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 63.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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), Cu 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.
