Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 239.66 g/mol gives (S)-Norfenfluramine Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(S)-Norfenfluramine Hydrochloride (CAS 37936-89-3), molecular formula C10H12F3NHCl and molecular weight 239.66 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine/chlorine substitution, (S)-Norfenfluramine Hydrochloride is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 239.66 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), (S)-Norfenfluramine Hydrochloride 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.
