Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Chloro-9H-2,4,9-triaza-fluorene (CAS 98792-02-0), molecular formula C10H6ClN3 and molecular weight 203.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 1-Chloro-9H-2,4,9-triaza-fluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 203.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 1-Chloro-9H-2,4,9-triaza-fluorene 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.
