Chemical Structure
Description
CATO supplies 3,4-Dimethyl-1-(p-tolyl)pyrano[2,3-c]pyrazol-6(1H)-one (CAS 74169-53-2), a certified reference material (molecular formula C15H14N2O2, MW 254.28 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Dimethyl-1-(p-tolyl)pyrano[2,3-c]pyrazol-6(1H)-one (C15H14N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3,4-Dimethyl-1-(p-tolyl)pyrano[2,3-c]pyrazol-6(1H)-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.
