Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.13 g/mol gives 1-(2-Bromophenyl)cyclopentanecarboxylic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Bromophenyl)cyclopentanecarboxylic Acid (CAS 143328-22-7), molecular formula C12H13BrO2 and molecular weight 269.13 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Bromophenyl)cyclopentanecarboxylic Acid (C12H13BrO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 1-(2-Bromophenyl)cyclopentanecarboxylic 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.
