Ethambutol-d4 Dihydrochloride CAS 1129526-19-7

Description

The occurrence of Ethambutol-d4 Dihydrochloride is closely related to deuterium isotope labeling, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethambutol-d4 Dihydrochloride (CAS 1129526-19-7), molecular formula C10H20D4N2O2HCl and molecular weight 244.80 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H20D4N2O2HCl, Ethambutol-d4 Dihydrochloride contains deuterium isotope labeling, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 244.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
