Chemical Structure
Description
As a certified reference material (CRM), Methyl 3-(3-bromophenyl)prop-2-ynoate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Methyl 3-(3-bromophenyl)prop-2-ynoate (CAS 204459-05-2), molecular formula C10H7BrO2 and molecular weight 239.07 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 3-(3-bromophenyl)prop-2-ynoate (C10H7BrO2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
