Description
CATO supplies Isoxazole, 4-(chloromethyl)-5-methyl-3-phenyl- (CAS 18718-83-7), a certified reference material (molecular formula C11H10ClNO, MW 207.66 g/mol) for analytical method development and quality control.
Structurally, Isoxazole, 4-(chloromethyl)-5-methyl-3-phenyl- (C11H10ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 207.66 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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 Isoxazole, 4-(chloromethyl)-5-methyl-3-phenyl- 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.
