Chemical Structure

Methyl 2-(2-chlorobenzamido)-5-((2,5-dimethylphenyl)carbamoyl)-4-methylthiophene-3-carboxylate CAS 335407-55-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 2-(2-chlorobenzamido)-5-((2,5-dimethylphenyl)carbamoyl)-4-methylthiophene-3-carboxylate.

Methyl 2-(2-chlorobenzamido)-5-((2,5-dimethylphenyl)carbamoyl)-4-methylthiophene-3-carboxylate (CAS 335407-55-1) is a high-purity analytical reference standard with the molecular formula C23H21ClN2O4S and a molecular weight of 456.94 g/mol.

Structurally, Methyl 2-(2-chlorobenzamido)-5-((2,5-dimethylphenyl)carbamoyl)-4-methylthiophene-3-carboxylate (C23H21ClN2O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 456.94 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.

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.
