Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 136.12 g/mol gives 5-Ethynyl-2-fluorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Ethynyl-2-fluorophenol (CAS 1062617-98-4) is a high-purity analytical reference standard with the molecular formula C8H5FO and a molecular weight of 136.12 g/mol.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 5-Ethynyl-2-fluorophenol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 136.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-Ethynyl-2-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.
