Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 9-(Difluoromethyl)phenanthrene (CAS 1186195-18-5), a certified reference material (molecular formula C15H10F2, MW 228.24 g/mol) for analytical method development and quality control.
Structurally, 9-(Difluoromethyl)phenanthrene (C15H10F2) contains fluorine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 228.24 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.
As a certified reference material (CRM), 9-(Difluoromethyl)phenanthrene 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.
