Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-cyclohexyl-1-(4-hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)piperidine-3-carboxamide.
N-cyclohexyl-1-(4-hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)piperidine-3-carboxamide (CAS 1242873-50-2), molecular formula C24H28N4O2S and molecular weight 436.57 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-cyclohexyl-1-(4-hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)piperidine-3-carboxamide (C24H28N4O2S) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), N-cyclohexyl-1-(4-hydroxy-7-phenylthieno[3,2-d]pyrimidin-2-yl)piperidine-3-carboxamide 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.
