Isoxazole, 4-(bromomethyl)-5-cyclopropyl-3-(2,6-dichlorophenyl)- CAS 946426-94-4 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 Isoxazole, 4-(bromomethyl)-5-cyclopropyl-3-(2,6-dichlorophenyl)-.

Isoxazole, 4-(bromomethyl)-5-cyclopropyl-3-(2,6-dichlorophenyl)- (CAS 946426-94-4), molecular formula C13H10BrCl2NO and molecular weight 347.03 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, chlorine/bromine substitution, Isoxazole, 4-(bromomethyl)-5-cyclopropyl-3-(2,6-dichlorophenyl)- is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.03 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), Isoxazole, 4-(bromomethyl)-5-cyclopropyl-3-(2,6-dichlorophenyl)- 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.
