2,6-Dimethyl-3-hydroxypyridine CAS 1122-43-6

Description

The occurrence of 2,6-Dimethyl-3-hydroxypyridine is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,6-Dimethyl-3-hydroxypyridine (CAS 1122-43-6), molecular formula C7H9NO and molecular weight 123.15 g/mol, is a CATO reference standard with documented purity and traceability.

2,6-Dimethyl-3-hydroxypyridine (C7H9NO) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
