Chemical Structure

Copper(II) selenite dihydrate CAS 15168-20-4 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 Copper(II) selenite dihydrate.

Copper(II) selenite dihydrate (CAS 15168-20-4), molecular formula O3SeCuH2O and molecular weight 208.53 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Copper(II) selenite dihydrate (O3SeCuH2O) is characterized by an inorganic composition. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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), Copper(II) selenite dihydrate 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.
