Description

The occurrence of 2,2 inverted exclamation marka-Bipyridine 1-oxide 2,2 inverted exclamation marka-Bipyridine N-oxide 2,2 inverted exclamation marka-Bipyridine monooxide 2,2 inverted exclamation marka-Bipyridyl N-oxide 2,2 inverted exclamation marka-Dipyridyl 1-oxide 2,2 inverted exclamation marka-Dipyridyl N-oxide 33421-43-1 is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2 inverted exclamation marka-Bipyridine 1-oxide 2,2 inverted exclamation marka-Bipyridine N-oxide 2,2 inverted exclamation marka-Bipyridine monooxide 2,2 inverted exclamation marka-Bipyridyl N-oxide 2,2 inverted exclamation marka-Dipyridyl 1-oxide 2,2 inverted exclamation marka-Dipyridyl N-oxide 33421-43-1 (CAS 33421-43-1), molecular formula C10H19N2O and molecular weight 183.27 g/mol, is a CATO reference standard with documented purity and traceability.

2,2 inverted exclamation marka-Bipyridine 1-oxide 2,2 inverted exclamation marka-Bipyridine N-oxide 2,2 inverted exclamation marka-Bipyridine monooxide 2,2 inverted exclamation marka-Bipyridyl N-oxide 2,2 inverted exclamation marka-Dipyridyl 1-oxide 2,2 inverted exclamation marka-Dipyridyl N-oxide 33421-43-1 (C10H19N2O) contains an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
