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.
CATO supplies 8-(3-Bromophenyl)-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-6-one (CAS 867068-21-1), a certified reference material (molecular formula C18H12BrNO4, MW 386.20 g/mol) for analytical method development and quality control.
8-(3-Bromophenyl)-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-6-one (C18H12BrNO4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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.
CATO manufactures 8-(3-Bromophenyl)-5,12,14-trioxa-2-azatetracyclo[7.7.0.0^{3,7}.0^{11,15}]hexadeca-1(9),3(7),10,15-tetraen-6-one 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.
