Chemical Structure

Calcium bromide, monohydrate CAS 62648-72-0 chemical structure

Description

Calcium bromide, monohydrate (CAS 62648-72-0), molecular formula Br2CaH2O and molecular weight 217.90 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a salt form, bromine substitution, Calcium bromide, monohydrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.90 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
