Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1S,2R)-Ethyl 2-(((R)-1-phenylethyl)amino)cyclohexanecarboxylate 4-methylbenzenesulfonate.
CATO supplies (1S,2R)-Ethyl 2-(((R)-1-phenylethyl)amino)cyclohexanecarboxylate 4-methylbenzenesulfonate (CAS 1105703-25-0), a certified reference material (molecular formula C17H25NO2C7H8O3S, MW 447.59 g/mol) for analytical method development and quality control.
(1S,2R)-Ethyl 2-(((R)-1-phenylethyl)amino)cyclohexanecarboxylate 4-methylbenzenesulfonate (C17H25NO2C7H8O3S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
