Chemical Structure

2-((3-Fluoro-4-methylphenyl)amino)-2-oxoethyl 3-methylthiophene-2-carboxylate CAS 733018-59-2 chemical structure

Description

The occurrence of 2-((3-Fluoro-4-methylphenyl)amino)-2-oxoethyl 3-methylthiophene-2-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-((3-Fluoro-4-methylphenyl)amino)-2-oxoethyl 3-methylthiophene-2-carboxylate (CAS 733018-59-2), molecular formula C15H14FNO3S and molecular weight 307.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-((3-Fluoro-4-methylphenyl)amino)-2-oxoethyl 3-methylthiophene-2-carboxylate (C15H14FNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 307.34 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

CATO manufactures 2-((3-Fluoro-4-methylphenyl)amino)-2-oxoethyl 3-methylthiophene-2-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
