Chemical Structure
Description
As a certified reference material (CRM), 7-Fluoroindoline hydrochloride 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.
7-Fluoroindoline hydrochloride (CAS 1820711-83-8), molecular formula C8H8FNHCl and molecular weight 173.62 g/mol, is a CATO reference standard with documented purity and traceability.
7-Fluoroindoline hydrochloride (C8H8FNHCl) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
