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-(2-Azidoethoxy)-2-(2-chlorobenzylidene)-3-oxobutanoic Acid Ethyl Ester 4-(2-Azidoethoxy)-2-[(2-chlorophenyl)methylene]-3-oxo-butanoic Acid Ethyl Ester 837427-86-8 Ethyl (2-Azidoethoxy)aceto-2-(2-chlorophenylmethlene)acetate (CAS 837427-86-8) is a high-purity analytical reference standard with the molecular formula C15H16ClN3O4 and a molecular weight of 337.76 g/mol.

4-(2-Azidoethoxy)-2-(2-chlorobenzylidene)-3-oxobutanoic Acid Ethyl Ester 4-(2-Azidoethoxy)-2-[(2-chlorophenyl)methylene]-3-oxo-butanoic Acid Ethyl Ester 837427-86-8 Ethyl (2-Azidoethoxy)aceto-2-(2-chlorophenylmethlene)acetate (C15H16ClN3O4) contains a flavonoid core, 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.
