2-Bromo-1-(2,4-dihydroxyphenyl)ethan-1-one 2-Bromo-2',4'-dihydroxyacetophenone 2-bromo-1-(2,4-dihydroxyphenyl)ethanone 2491-39-6 4-(Bromoacetyl)resorcinol CAS 2491-39-6 chemical structure

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-1-(2,4-dihydroxyphenyl)ethan-1-one 2-Bromo-2',4'-dihydroxyacetophenone 2-bromo-1-(2,4-dihydroxyphenyl)ethanone 2491-39-6 4-(Bromoacetyl)resorcinol.

2-Bromo-1-(2,4-dihydroxyphenyl)ethan-1-one 2-Bromo-2',4'-dihydroxyacetophenone 2-bromo-1-(2,4-dihydroxyphenyl)ethanone 2491-39-6 4-(Bromoacetyl)resorcinol (CAS 2491-39-6), molecular formula C8H13BrO3 and molecular weight 237.09 g/mol, is a CATO reference standard with documented purity and traceability.

2-Bromo-1-(2,4-dihydroxyphenyl)ethan-1-one 2-Bromo-2',4'-dihydroxyacetophenone 2-bromo-1-(2,4-dihydroxyphenyl)ethanone 2491-39-6 4-(Bromoacetyl)resorcinol (C8H13BrO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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-1-(2,4-dihydroxyphenyl)ethan-1-one 2-Bromo-2',4'-dihydroxyacetophenone 2-bromo-1-(2,4-dihydroxyphenyl)ethanone 2491-39-6 4-(Bromoacetyl)resorcinol 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.
