Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution, 9-Fluoro-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 190.22 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).
9-Fluoro-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (CAS 177858-82-1) is a high-purity analytical reference standard with the molecular formula C11H11FN2 and a molecular weight of 190.22 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
