Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(2,4-dichloro-5-isopropoxyphenyl)-3-(2-nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxamide.
N-(2,4-dichloro-5-isopropoxyphenyl)-3-(2-nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxamide (CAS 339015-68-8), molecular formula C21H15Cl2F3N2O5S and molecular weight 535.32 g/mol, is a CATO reference standard with documented purity and traceability.
N-(2,4-dichloro-5-isopropoxyphenyl)-3-(2-nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxamide (C21H15Cl2F3N2O5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures N-(2,4-dichloro-5-isopropoxyphenyl)-3-(2-nitro-4-(trifluoromethyl)phenoxy)thiophene-2-carboxamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
