Description
As a certified reference material (CRM), rac Demethyl Citalopram-d3 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.
CATO supplies rac Demethyl Citalopram-d3 (CAS 1189490-71-8), a certified reference material (molecular formula C19H16D3FN2O, MW 313.38 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H16D3FN2O, rac Demethyl Citalopram-d3 contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 313.38 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
