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.
Bromophenol red sodium salt (CAS 102185-50-2), molecular formula C19H11Br2O5SNa and molecular weight 534.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, Bromophenol red sodium salt is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 534.15 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.
CATO manufactures Bromophenol red sodium salt 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.
