Chemical Structure

5-Butyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one CAS 107417-09-4 chemical structure

Description

5-Butyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one (CAS 107417-09-4), molecular formula C13H16N2O and molecular weight 216.28 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-Butyl-2-phenyl-2,4-dihydro-3H-pyrazol-3-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 216.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 5-Butyl-2-phenyl-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.
