Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 298.40 g/mol gives Despropionyl p-fluorofentanyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Despropionyl p-fluorofentanyl (CAS 122861-41-0), molecular formula C19H23FN2 and molecular weight 298.40 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C19H23FN2, Despropionyl p-fluorofentanyl contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.40 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Despropionyl p-fluorofentanyl 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.
