Compared with other compounds in its class, the molecular weight of 299.68 g/mol gives N-(4-chloro-5-cyanothiazol-2-yl)-3,4-difluorobenzamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies N-(4-chloro-5-cyanothiazol-2-yl)-3,4-difluorobenzamide (CAS 866154-05-4), a certified reference material (molecular formula C11H4ClF2N3OS, MW 299.68 g/mol) for analytical method development and quality control.
N-(4-chloro-5-cyanothiazol-2-yl)-3,4-difluorobenzamide (C11H4ClF2N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-(4-chloro-5-cyanothiazol-2-yl)-3,4-difluorobenzamide 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.
