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-Methyl-2-oxo-1,2,3,4-tetrahydroquinoxalin-6-yl)boronic acid (CAS 305790-80-1), molecular formula C9H11BN2O3 and molecular weight 206.01 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4-Methyl-2-oxo-1,2,3,4-tetrahydroquinoxalin-6-yl)boronic acid (C9H11BN2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.5, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 206.01 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
