Chemical Structure
Description
CATO supplies 5-Bromo-3,4-dihydroisoquinolin-1(2H)-one (CAS 1109230-25-2), a certified reference material (molecular formula C9H8BrNO, MW 226.07 g/mol) for analytical method development and quality control.
5-Bromo-3,4-dihydroisoquinolin-1(2H)-one (C9H8BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point; 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.
CATO manufactures 5-Bromo-3,4-dihydroisoquinolin-1(2H)-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.
