Chemical Structure
Description
3-Ethynyl-3-fluoropyrrolidine (CAS 1565079-79-9) is a high-purity analytical reference standard with the molecular formula C6H8FN and a molecular weight of 113.13 g/mol.
Owing to a nitrile group, fluorine substitution, 3-Ethynyl-3-fluoropyrrolidine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 113.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 3-Ethynyl-3-fluoropyrrolidine 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.
