Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((1-Cyanocyclohexyl)(methyl)amino)-2-oxoethyl 6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate.
2-((1-Cyanocyclohexyl)(methyl)amino)-2-oxoethyl 6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (CAS 1012177-75-1), molecular formula C20H26N2O3S and molecular weight 374.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((1-Cyanocyclohexyl)(methyl)amino)-2-oxoethyl 6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxylate (C20H26N2O3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 2-((1-Cyanocyclohexyl)(methyl)amino)-2-oxoethyl 6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-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.
