Description
Desmethyl Nefopam-D5 HCl (CAS 147656-98-2 (unlabeled)), molecular formula C16H12D5NOHCl and molecular weight 280.81 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C16H12D5NOHCl, Desmethyl Nefopam-D5 HCl contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Desmethyl Nefopam-D5 HCl 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.
