Chemical Structure
Description
Dexmedetomidine-d4 L-Tartrate (d4-Major) (CAS CATO-CCAD302491), molecular formula C13H12D4N2C4H6O6 and molecular weight 354.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Dexmedetomidine-d4 L-Tartrate (d4-Major) (C13H12D4N2C4H6O6) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
