Chemical Structure
Description
1-(2-Chlorophenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (CAS 1416340-88-9) is a high-purity analytical reference standard with the molecular formula C11H7ClN4OS and a molecular weight of 278.72 g/mol.
1-(2-Chlorophenyl)-6-mercapto-1H-pyrazolo[3,4-d]pyrimidin-4(5H)-one (C11H7ClN4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 1-(2-Chlorophenyl)-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.
