Chemical Structure
Description
CATO supplies 4-(2-Methoxy-5-methylphenyl)-4-oxo-butyric acid (CAS 55007-22-2), a certified reference material (molecular formula C12H14O4, MW 222.24 g/mol) for analytical method development and quality control.
4-(2-Methoxy-5-methylphenyl)-4-oxo-butyric acid (C12H14O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
As a certified reference material (CRM), 4-(2-Methoxy-5-methylphenyl)-4-oxo-butyric acid 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.
