Chemical Structure

1-Methyl-4-oxo-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine-6-carboxylic acid CAS 1029420-83-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 194.15 g/mol gives 1-Methyl-4-oxo-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine-6-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-Methyl-4-oxo-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine-6-carboxylic acid (CAS 1029420-83-4), molecular formula C7H6N4O3 and molecular weight 194.15 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methyl-4-oxo-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine-6-carboxylic acid (C7H6N4O3) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.

CATO manufactures 1-Methyl-4-oxo-4,5-dihydro-1H-pyrazolo[3,4-d]pyrimidine-6-carboxylic acid 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.
