(2,3-Dioxo-2,3-dihydro-1H-indol-1-yl)-methylchloroacetate (CAS 40693-49-0), molecular formula C11H8ClNO4 and molecular weight 253.64 g/mol, is a CATO reference standard with documented purity and traceability.
(2,3-Dioxo-2,3-dihydro-1H-indol-1-yl)-methylchloroacetate (C11H8ClNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
