Chemical Structure
Description
Methyl 2-(quinoxalin-2-yloxy)benzoate (CAS 338394-68-6), molecular formula C16H12N2O3 and molecular weight 280.28 g/mol, is a CATO reference standard with documented purity and traceability.
Methyl 2-(quinoxalin-2-yloxy)benzoate (C16H12N2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
CATO manufactures Methyl 2-(quinoxalin-2-yloxy)benzoate 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.
