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 1-(3-Chloro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one.
CATO supplies 1-(3-Chloro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 1416340-96-9), a certified reference material (molecular formula C12H9ClN4OS, MW 292.74 g/mol) for analytical method development and quality control.
The molecular framework of 1-(3-Chloro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C12H9ClN4OS) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 1-(3-Chloro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one 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.
