2-Bromo-3-(4-(methylsulfonyl)phenyl)cyclopent-2-en-1-one CAS 190966-44-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Bromo-3-(4-(methylsulfonyl)phenyl)cyclopent-2-en-1-one.

2-Bromo-3-(4-(methylsulfonyl)phenyl)cyclopent-2-en-1-one (CAS 190966-44-0) is a high-purity analytical reference standard with the molecular formula C12H11BrO3S and a molecular weight of 315.18 g/mol.

2-Bromo-3-(4-(methylsulfonyl)phenyl)cyclopent-2-en-1-one (C12H11BrO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, 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 2-Bromo-3-(4-(methylsulfonyl)phenyl)cyclopent-2-en-1-one 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.
