Chemical Structure
Description
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.
4-(Chloromethyl)-5-ethyl-3-methylisoxazole (CAS 2126160-22-1), molecular formula C7H10ClNO and molecular weight 159.61 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Chloromethyl)-5-ethyl-3-methylisoxazole (C7H10ClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4-(Chloromethyl)-5-ethyl-3-methylisoxazole 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.
