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 [5-(4-Chlorophenyl)isoxazol-3-yl]acetic acid.
CATO supplies [5-(4-Chlorophenyl)isoxazol-3-yl]acetic acid (CAS 24146-84-7), a certified reference material (molecular formula C11H8ClNO3, MW 237.64 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H8ClNO3, [5-(4-Chlorophenyl)isoxazol-3-yl]acetic acid contains a nitrogen-containing heterocyclic scaffold, 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 237.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), [5-(4-Chlorophenyl)isoxazol-3-yl]acetic acid 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.
