Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies N-Desmethyl Diphenhydramine-d3 Hydrochloride (CAS 1794759-12-8), a certified reference material (molecular formula C16H16D3NOHCl, MW 280.81 g/mol) for analytical method development and quality control.
Based on its molecular formula C16H16D3NOHCl, N-Desmethyl Diphenhydramine-d3 Hydrochloride 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
