CATO supplies (5-BROMOTHIEN-2-YL)(PHENYL)METHANONE (5-BROMOTHIOPHEN-2-YL)(PHENYL)METHANONE 2-BENZOYL-5-BROMOTHIOPHENE 2-BROMO-5-BENZOYLTHIOPHENE 31161-46-3 BC003772 (CAS 31161-46-3), a certified reference material (molecular formula C11H7BrOS, MW 267.14 g/mol) for analytical method development and quality control.
Structurally, (5-BROMOTHIEN-2-YL)(PHENYL)METHANONE (5-BROMOTHIOPHEN-2-YL)(PHENYL)METHANONE 2-BENZOYL-5-BROMOTHIOPHENE 2-BROMO-5-BENZOYLTHIOPHENE 31161-46-3 BC003772 (C11H7BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 267.14 g/mol, it falls into the medium-molecular-weight range. 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.
