Chemical Structure

Calcium perrhenate CAS 13768-54-2 chemical structure

Description

The occurrence of Calcium perrhenate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Calcium perrhenate (CAS 13768-54-2), molecular formula O4ReCa and molecular weight 290.28 g/mol, is a CATO reference standard with documented purity and traceability.

Calcium perrhenate (O4ReCa) contains an inorganic composition. It is notably hygroscopic; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
