Chemical Structure

1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone oxime CAS 1019075-43-4 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.

1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone oxime (CAS 1019075-43-4) is a high-purity analytical reference standard with the molecular formula C12H13N3O and a molecular weight of 215.25 g/mol.

1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone oxime (C12H13N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1-(5-methyl-1-phenyl-1H-pyrazol-4-yl)ethanone oxime 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.
