Chemical Structure
Description
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 supplies 4-(2-(Allyloxy)benzylidene)-2,5-diphenyl-2,4-dihydro-3H-pyrazol-3-one (CAS 112296-85-2), a certified reference material (molecular formula C25H20N2O2, MW 380.44 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(2-(Allyloxy)benzylidene)-2,5-diphenyl-2,4-dihydro-3H-pyrazol-3-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 4-(2-(Allyloxy)benzylidene)-2,5-diphenyl-2,4-dihydro-3H-pyrazol-3-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.
