(E)-4-(3-(thiophen-2-yl)acryloyl)phenyl 4-bromobenzenesulfonate CAS 297150-18-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-(3-(thiophen-2-yl)acryloyl)phenyl 4-bromobenzenesulfonate.

(E)-4-(3-(thiophen-2-yl)acryloyl)phenyl 4-bromobenzenesulfonate (CAS 297150-18-6), molecular formula C19H13BrO4S2 and molecular weight 449.34 g/mol, is a CATO reference standard with documented purity and traceability.

(E)-4-(3-(thiophen-2-yl)acryloyl)phenyl 4-bromobenzenesulfonate (C19H13BrO4S2) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures (E)-4-(3-(thiophen-2-yl)acryloyl)phenyl 4-bromobenzenesulfonate 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.
