Chemical Structure
Description
CATO supplies Choline-d13 Chloride (N,N,N-trimethyl-d9; 1,1,2,2-d4) (CAS 352438-97-2), a certified reference material (molecular formula C5HD13NOCl, MW 152.70 g/mol) for analytical method development and quality control.
Based on its molecular formula C5HD13NOCl, Choline-d13 Chloride (N,N,N-trimethyl-d9; 1,1,2,2-d4) contains deuterium isotope labeling, 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 152.70 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
