Chemical Structure
Description
The occurrence of 2-Hydrazinyl-6-methyl-3-nitropyridine is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Hydrazinyl-6-methyl-3-nitropyridine (CAS 21901-30-4) is a high-purity analytical reference standard with the molecular formula C6H8N4O2 and a molecular weight of 168.15 g/mol.
The molecular framework of 2-Hydrazinyl-6-methyl-3-nitropyridine (C6H8N4O2) is characterized by an amino-acid-derived structure, 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.
