Methyl (Z)-3-((5,5,5-trifluoro-4-oxopent-2-en-2-yl)amino)thiophene-2-carboxylate CAS 882747-69-5 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 (Z)-3-((5,5,5-trifluoro-4-oxopent-2-en-2-yl)amino)thiophene-2-carboxylate.

Methyl (Z)-3-((5,5,5-trifluoro-4-oxopent-2-en-2-yl)amino)thiophene-2-carboxylate (CAS 882747-69-5) is a high-purity analytical reference standard with the molecular formula C11H10F3NO3S and a molecular weight of 293.26 g/mol.

Methyl (Z)-3-((5,5,5-trifluoro-4-oxopent-2-en-2-yl)amino)thiophene-2-carboxylate (C11H10F3NO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
