tert-Butyl 4-(5-(4-chlorophenyl)-4-(pyrimidin-4-yl)-1-tosyl-1h-pyrazol-3-yl)piperidine-1-carboxylate (CAS 503443-67-2) is a high-purity analytical reference standard with the molecular formula C30H32ClN5O4S and a molecular weight of 594.12 g/mol.
The molecular framework of tert-Butyl 4-(5-(4-chlorophenyl)-4-(pyrimidin-4-yl)-1-tosyl-1h-pyrazol-3-yl)piperidine-1-carboxylate (C30H32ClN5O4S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), tert-Butyl 4-(5-(4-chlorophenyl)-4-(pyrimidin-4-yl)-1-tosyl-1h-pyrazol-3-yl)piperidine-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.
