Description
CATO manufactures 2-Bromo-1-(3-methoxyisoxazol-5-yl)ethanone 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-Bromo-1-(3-methoxyisoxazol-5-yl)ethanone (CAS 104164-49-0), a certified reference material (molecular formula C6H6BrNO3, MW 220.02 g/mol) for analytical method development and quality control.
2-Bromo-1-(3-methoxyisoxazol-5-yl)ethanone (C6H6BrNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
