Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Fluoro-2,3,4,9-tetrahydro-1h-carbazol-1-one.
8-Fluoro-2,3,4,9-tetrahydro-1h-carbazol-1-one (CAS 76255-89-5), molecular formula C12H10FNO and molecular weight 203.21 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H10FNO, 8-Fluoro-2,3,4,9-tetrahydro-1h-carbazol-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 203.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
