Chemical Structure

3-(2-Chlorophenyl)-5-methyl-N-(2,4,4-trimethylpentan-2-yl)isoxazole-4-carboxamide CAS 895852-30-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(2-Chlorophenyl)-5-methyl-N-(2,4,4-trimethylpentan-2-yl)isoxazole-4-carboxamide.

CATO supplies 3-(2-Chlorophenyl)-5-methyl-N-(2,4,4-trimethylpentan-2-yl)isoxazole-4-carboxamide (CAS 895852-30-9), a certified reference material (molecular formula C19H25ClN2O2, MW 348.87 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(2-Chlorophenyl)-5-methyl-N-(2,4,4-trimethylpentan-2-yl)isoxazole-4-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 348.87 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.

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.

As a certified reference material (CRM), 3-(2-Chlorophenyl)-5-methyl-N-(2,4,4-trimethylpentan-2-yl)isoxazole-4-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
