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-(4-(1H-Tetrazol-1-yl)phenyl)-1-(2-chlorobenzyl)-3-methyl-1H-thieno[2,3-c]pyrazole-5-carboxamide.
CATO supplies N-(4-(1H-Tetrazol-1-yl)phenyl)-1-(2-chlorobenzyl)-3-methyl-1H-thieno[2,3-c]pyrazole-5-carboxamide (CAS 854032-30-7), a certified reference material (molecular formula C21H16ClN7OS, MW 449.92 g/mol) for analytical method development and quality control.
The molecular framework of N-(4-(1H-Tetrazol-1-yl)phenyl)-1-(2-chlorobenzyl)-3-methyl-1H-thieno[2,3-c]pyrazole-5-carboxamide (C21H16ClN7OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, 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. 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-(4-(1H-Tetrazol-1-yl)phenyl)-1-(2-chlorobenzyl)-3-methyl-1H-thieno[2,3-c]pyrazole-5-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.
