Description
As a certified reference material (CRM), 9-Oxo-9H-fluorene-1-carbaldehyde 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.
CATO supplies 9-Oxo-9H-fluorene-1-carbaldehyde (CAS 5385-56-8), a certified reference material (molecular formula C14H8O2, MW 208.21 g/mol) for analytical method development and quality control.
Structurally, 9-Oxo-9H-fluorene-1-carbaldehyde (C14H8O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 208.21 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
