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-((5,6-dimethyl-2H-pyran-2-yl)(ethoxy)amino)-5-((4-(ethoxycarbonyl)phenyl)carbamoyl)-4-methylthiophene-3-carboxylate.
Methyl 2-((5,6-dimethyl-2H-pyran-2-yl)(ethoxy)amino)-5-((4-(ethoxycarbonyl)phenyl)carbamoyl)-4-methylthiophene-3-carboxylate (CAS 335407-47-1) is a high-purity analytical reference standard with the molecular formula C26H30N2O7S and a molecular weight of 514.59 g/mol.
The molecular framework of Methyl 2-((5,6-dimethyl-2H-pyran-2-yl)(ethoxy)amino)-5-((4-(ethoxycarbonyl)phenyl)carbamoyl)-4-methylthiophene-3-carboxylate (C26H30N2O7S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
