Description
6-chloro-4-fluoro-1H-indole (CAS 885520-88-7), molecular formula C8H13ClFN and molecular weight 177.65 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/chlorine substitution, 6-chloro-4-fluoro-1H-indole is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 177.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 6-chloro-4-fluoro-1H-indole 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.
