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 3,4-Dimethylpyrano[2,3-c]pyrazol-6(1H)-one.
3,4-Dimethylpyrano[2,3-c]pyrazol-6(1H)-one (CAS 5203-98-5) is a high-purity analytical reference standard with the molecular formula C8H8N2O2 and a molecular weight of 164.16 g/mol.
The molecular framework of 3,4-Dimethylpyrano[2,3-c]pyrazol-6(1H)-one (C8H8N2O2) 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 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.
CATO manufactures 3,4-Dimethylpyrano[2,3-c]pyrazol-6(1H)-one 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.
