Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-[3-(Methylsulfonyl)phenyl]cyclopentanecarbonitrile.
1-[3-(Methylsulfonyl)phenyl]cyclopentanecarbonitrile (CAS 2120495-01-2), molecular formula C13H15NO2S and molecular weight 249.33 g/mol, is a CATO reference standard with documented purity and traceability.
1-[3-(Methylsulfonyl)phenyl]cyclopentanecarbonitrile (C13H15NO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-[3-(Methylsulfonyl)phenyl]cyclopentanecarbonitrile 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.
