4-[(1Z)-3-Oxo-3-phenylprop-1-en-1-yl]phenyl 4-bromobenzene-1-sulfonate CAS 298215-90-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(1Z)-3-Oxo-3-phenylprop-1-en-1-yl]phenyl 4-bromobenzene-1-sulfonate.

4-[(1Z)-3-Oxo-3-phenylprop-1-en-1-yl]phenyl 4-bromobenzene-1-sulfonate (CAS 298215-90-4), molecular formula C21H15BrO4S and molecular weight 443.31 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, 4-[(1Z)-3-Oxo-3-phenylprop-1-en-1-yl]phenyl 4-bromobenzene-1-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 443.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 4-[(1Z)-3-Oxo-3-phenylprop-1-en-1-yl]phenyl 4-bromobenzene-1-sulfonate 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.
