Compared with other compounds in its class, the molecular weight of 196.29 g/mol gives Ethyl (2R)-2-methyl-5-(propan-2-ylidene)cyclopentane-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Ethyl (2R)-2-methyl-5-(propan-2-ylidene)cyclopentane-1-carboxylate (CAS 623935-92-2), a certified reference material (molecular formula C12H20O2, MW 196.29 g/mol) for analytical method development and quality control.
Ethyl (2R)-2-methyl-5-(propan-2-ylidene)cyclopentane-1-carboxylate (C12H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), Ethyl (2R)-2-methyl-5-(propan-2-ylidene)cyclopentane-1-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.
