Ethyl 2-(2-chloroacetamido)-5-methyl-4-(2-methylbutyl)thiophene-3-carboxylate CAS 733031-09-9 chemical structure

Description

The occurrence of Ethyl 2-(2-chloroacetamido)-5-methyl-4-(2-methylbutyl)thiophene-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 2-(2-chloroacetamido)-5-methyl-4-(2-methylbutyl)thiophene-3-carboxylate (CAS 733031-09-9) is a high-purity analytical reference standard with the molecular formula C15H22ClNO3S and a molecular weight of 331.86 g/mol.

Ethyl 2-(2-chloroacetamido)-5-methyl-4-(2-methylbutyl)thiophene-3-carboxylate (C15H22ClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.
