Chemical Structure
Description
The occurrence of 2-Ethyl-5-fluorophenol is closely related to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Ethyl-5-fluorophenol (CAS 1147351-77-6), molecular formula C8H9FO and molecular weight 140.15 g/mol, is a CATO reference standard with documented purity and traceability.
2-Ethyl-5-fluorophenol (C8H9FO) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 2-Ethyl-5-fluorophenol 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.
