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 3-((3-(trifluoromethyl)benzyl)oxy)thieno[2,3-b]pyridine-2-carboxylate.
Methyl 3-((3-(trifluoromethyl)benzyl)oxy)thieno[2,3-b]pyridine-2-carboxylate (CAS 338419-35-5) is a high-purity analytical reference standard with the molecular formula C17H12F3NO3S and a molecular weight of 367.34 g/mol.
The molecular framework of Methyl 3-((3-(trifluoromethyl)benzyl)oxy)thieno[2,3-b]pyridine-2-carboxylate (C17H12F3NO3S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.
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.
