Description
CATO supplies 2-Demethoxy-2-chloro Urapidil-d4 (CAS 1794883-40-1), a certified reference material (molecular formula C19H22D4ClN5O2, MW 395.92 g/mol) for analytical method development and quality control.
Based on its molecular formula C19H22D4ClN5O2, 2-Demethoxy-2-chloro Urapidil-d4 contains deuterium isotope labeling, a steroid core, 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 395.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2-Demethoxy-2-chloro Urapidil-d4 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.
