Chemical Structure
Description
Structurally, 1142204-47-4 9303AC C18H18Cl2N2O4 [{2-[(3,4-Dichlorobenzyl)amino]-2-oxoethyl} (4-methoxyphenyl)amino]acetic acid (C18H18Cl2N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 397.25 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).
1142204-47-4 9303AC C18H18Cl2N2O4 [{2-[(3,4-Dichlorobenzyl)amino]-2-oxoethyl} (4-methoxyphenyl)amino]acetic acid (CAS 1142204-47-4) is a high-purity analytical reference standard with the molecular formula C18H18Cl2N2O4 and a molecular weight of 397.25 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
