Chemical Structure
Description
(2Z)-2-[(2-Fluorophenyl)methylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one (CAS 1351509-64-2), molecular formula C19H14FNO and molecular weight 291.32 g/mol, is a CATO reference standard with documented purity and traceability.
(2Z)-2-[(2-Fluorophenyl)methylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one (C19H14FNO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), (2Z)-2-[(2-Fluorophenyl)methylidene]-2,3,4,9-tetrahydro-1H-carbazol-1-one 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.
