1159976-98-3 4-Chloro-5,6-dimethyl-3-pyridinemethanol 3-Acetate 1-Oxide 5-Acetoxymethyl-2,3-dimethyl-4-chloropyridine N-oxide CAS 1159976-98-3

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.

1159976-98-3 4-Chloro-5,6-dimethyl-3-pyridinemethanol 3-Acetate 1-Oxide 5-Acetoxymethyl-2,3-dimethyl-4-chloropyridine N-oxide (CAS 1159976-98-3), molecular formula C10H12ClNO3 and molecular weight 229.66 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H12ClNO3, 1159976-98-3 4-Chloro-5,6-dimethyl-3-pyridinemethanol 3-Acetate 1-Oxide 5-Acetoxymethyl-2,3-dimethyl-4-chloropyridine N-oxide contains 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 229.66 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).

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.
