Chemical Structure
Description
The occurrence of Methyl 3-(2,4-dichlorobenzamido)-4-methylthiophene-2-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.
Methyl 3-(2,4-dichlorobenzamido)-4-methylthiophene-2-carboxylate (CAS 866150-13-2), molecular formula C14H11Cl2NO3S and molecular weight 344.21 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Methyl 3-(2,4-dichlorobenzamido)-4-methylthiophene-2-carboxylate (C14H11Cl2NO3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
