Chemical Structure

9-Oxo-9H-fluorene-4-carbonitrile CAS 4269-20-9 chemical structure

Description

As a certified reference material (CRM), 9-Oxo-9H-fluorene-4-carbonitrile 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.

9-Oxo-9H-fluorene-4-carbonitrile (CAS 4269-20-9), molecular formula C14H7NO and molecular weight 205.21 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 9-Oxo-9H-fluorene-4-carbonitrile (C14H7NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 205.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
