Chemical Structure
Description
The occurrence of Methyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate (CAS 350989-74-1), a certified reference material (molecular formula C15H17NO2S, MW 275.37 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate (C15H17NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Methyl 2-amino-4-(3,4-dimethylphenyl)-5-methylthiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
