1-(4-Fluoro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one CAS 1416348-36-1

Description

1-(4-Fluoro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 1416348-36-1), molecular formula C12H9FN4OS and molecular weight 276.29 g/mol, is a CATO reference standard with documented purity and traceability.

1-(4-Fluoro-2-methylphenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C12H9FN4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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-(4-Fluoro-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.
