Chemical Structure
Description
The occurrence of Phosphorylcholine-d9 Chloride, Calcium Salt (N,N,N-trimethyl-d9) is closely related to deuterium isotope labeling, a salt form, a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Phosphorylcholine-d9 Chloride, Calcium Salt (N,N,N-trimethyl-d9) (CAS 344299-43-0), a certified reference material (molecular formula C5H6D9NO4PCaCl, MW 268.73 g/mol) for analytical method development and quality control.
The molecular framework of Phosphorylcholine-d9 Chloride, Calcium Salt (N,N,N-trimethyl-d9) (C5H6D9NO4PCaCl) is characterized by deuterium isotope labeling, a salt form, a carbohydrate-derived structure, an amide group, a phosphate ester group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
