Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 185.59 g/mol gives 3-Chloro-6-fluoro-1h-indazol-5-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-Chloro-6-fluoro-1h-indazol-5-amine (CAS 864082-73-5), molecular formula C7H5ClFN3 and molecular weight 185.59 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Chloro-6-fluoro-1h-indazol-5-amine (C7H5ClFN3) is characterized by a nitrile group, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3-Chloro-6-fluoro-1h-indazol-5-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
