Description
1142215-66-4 9467AC C21H23N3O4 [(2-{[2-(1H-Indol-3-yl)ethyl]amino}-2-oxoethyl)-(4-methoxyphenyl)amino]acetic acid (CAS 1142215-66-4), molecular formula C21H23N3O4 and molecular weight 381.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1142215-66-4 9467AC C21H23N3O4 [(2-{[2-(1H-Indol-3-yl)ethyl]amino}-2-oxoethyl)-(4-methoxyphenyl)amino]acetic acid (C21H23N3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 381.43 g/mol, it falls into the moderately-high-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).
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.
