The occurrence of 4,5-Difluoro-1H-indole-7-carbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4,5-Difluoro-1H-indole-7-carbonitrile (CAS 1167055-88-0), a certified reference material (molecular formula C9H4F2N2, MW 178.14 g/mol) for analytical method development and quality control.
4,5-Difluoro-1H-indole-7-carbonitrile (C9H4F2N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. Halogen substitution raises its density and boiling point; 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 4,5-Difluoro-1H-indole-7-carbonitrile 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.
