Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 313.19 g/mol gives 8-(3-Bromophenyl)-8-oxooctanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 8-(3-Bromophenyl)-8-oxooctanoic acid (CAS 898787-92-3), a certified reference material (molecular formula C14H17BrO3, MW 313.19 g/mol) for analytical method development and quality control.
8-(3-Bromophenyl)-8-oxooctanoic acid (C14H17BrO3) contains 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 8-(3-Bromophenyl)-8-oxooctanoic acid 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.
