The occurrence of Bromochlorophenol Blue sodium salt is closely related to a salt form, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Bromochlorophenol Blue sodium salt (CAS 102185-52-4) is a high-purity analytical reference standard with the molecular formula C19H9Br2Cl2O5SNa and a molecular weight of 603.03 g/mol.
Owing to a salt form, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, Bromochlorophenol Blue sodium salt is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 603.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), Bromochlorophenol Blue sodium salt 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.
