Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
copper chromite (CAS 12053-18-8) is a high-purity analytical reference standard with the molecular formula Cr2O3CuO and a molecular weight of 231.53 g/mol.
Owing to an inorganic composition, copper chromite is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO manufactures copper chromite under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
