Compared with other compounds in its class, the molecular weight of 451.52 g/mol gives 2-((2-Ethyl-6-(4-methylbenzyl)-7-oxo-6,7-dihydro-2H-pyrazolo[4,3-d]pyrimidin-5-yl)thio)-N-(2-fluorophenyl)acetamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-((2-Ethyl-6-(4-methylbenzyl)-7-oxo-6,7-dihydro-2H-pyrazolo[4,3-d]pyrimidin-5-yl)thio)-N-(2-fluorophenyl)acetamide (CAS 894920-92-4) is a high-purity analytical reference standard with the molecular formula C23H22FN5O2S and a molecular weight of 451.52 g/mol.
The molecular framework of 2-((2-Ethyl-6-(4-methylbenzyl)-7-oxo-6,7-dihydro-2H-pyrazolo[4,3-d]pyrimidin-5-yl)thio)-N-(2-fluorophenyl)acetamide (C23H22FN5O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 2-((2-Ethyl-6-(4-methylbenzyl)-7-oxo-6,7-dihydro-2H-pyrazolo[4,3-d]pyrimidin-5-yl)thio)-N-(2-fluorophenyl)acetamide 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.
