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 N-(1-(1-(3-Chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-3-methyl-1H-pyrazol-5-yl)cyclopentanecarboxamide.
N-(1-(1-(3-Chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-3-methyl-1H-pyrazol-5-yl)cyclopentanecarboxamide (CAS 1005925-62-1), molecular formula C21H20ClN7O and molecular weight 421.88 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(1-(1-(3-Chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-3-methyl-1H-pyrazol-5-yl)cyclopentanecarboxamide (C21H20ClN7O) is characterized by a steroid core, an amide 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. 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.
CATO manufactures N-(1-(1-(3-Chlorophenyl)-1H-pyrazolo[3,4-d]pyrimidin-4-yl)-3-methyl-1H-pyrazol-5-yl)cyclopentanecarboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
