6-Chloro-9a-(2-fluoroethyl)-7-methoxy-9,9a-dihydro-1H-fluoren-3(2H)-one CAS 1039456-85-3 chemical structure

Description

As a certified reference material (CRM), 6-Chloro-9a-(2-fluoroethyl)-7-methoxy-9,9a-dihydro-1H-fluoren-3(2H)-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.

6-Chloro-9a-(2-fluoroethyl)-7-methoxy-9,9a-dihydro-1H-fluoren-3(2H)-one (CAS 1039456-85-3) is a high-purity analytical reference standard with the molecular formula C16H16ClFO2 and a molecular weight of 294.75 g/mol.

Structurally, 6-Chloro-9a-(2-fluoroethyl)-7-methoxy-9,9a-dihydro-1H-fluoren-3(2H)-one (C16H16ClFO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 294.75 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.
