Description

CATO manufactures 2,2,2-Trichloro-1-(4-(3-(2,6-dichlorophenyl)-5-methylisoxazole-4-carbonyl)-1H-pyrrol-2-yl)ethan-1-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.

CATO supplies 2,2,2-Trichloro-1-(4-(3-(2,6-dichlorophenyl)-5-methylisoxazole-4-carbonyl)-1H-pyrrol-2-yl)ethan-1-one (CAS 478064-45-8), a certified reference material (molecular formula C17H9Cl5N2O3, MW 466.53 g/mol) for analytical method development and quality control.

Based on its molecular formula C17H9Cl5N2O3, 2,2,2-Trichloro-1-(4-(3-(2,6-dichlorophenyl)-5-methylisoxazole-4-carbonyl)-1H-pyrrol-2-yl)ethan-1-one contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 466.53 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
