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 3-[(cyanomethyl)sulfanyl]-N-(2,4-difluorophenyl)-2-thiophenecarboxamide 303150-86-9 KS-00002Z3E.
3-[(cyanomethyl)sulfanyl]-N-(2,4-difluorophenyl)-2-thiophenecarboxamide 303150-86-9 KS-00002Z3E (CAS 303150-86-9), molecular formula C13H8F2N2OS2 and molecular weight 310.34 g/mol, is a CATO reference standard with documented purity and traceability.
3-[(cyanomethyl)sulfanyl]-N-(2,4-difluorophenyl)-2-thiophenecarboxamide 303150-86-9 KS-00002Z3E (C13H8F2N2OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
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.
