2-Ethynyl-5-fluorophenol CAS 1882503-46-9 chemical structure

Description

As a certified reference material (CRM), 2-Ethynyl-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.

2-Ethynyl-5-fluorophenol (CAS 1882503-46-9), molecular formula C8H5FO and molecular weight 136.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-Ethynyl-5-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.
