Description
As a certified reference material (CRM), methyl 2,3-dimethyl-3-phenyloxirane-2-carboxylate 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.
CATO supplies methyl 2,3-dimethyl-3-phenyloxirane-2-carboxylate (CAS 99334-03-9), a certified reference material (molecular formula C12H14O3, MW 206.24 g/mol) for analytical method development and quality control.
methyl 2,3-dimethyl-3-phenyloxirane-2-carboxylate (C12H14O3) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
