Chemical Structure
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.
CATO supplies 3,4-Dichloro-N'-(4,6-dimethyl-3-(methylsulfonyl)pyridin-2-yl)-N'-methylbenzohydrazide (CAS 341967-40-6), a certified reference material (molecular formula C16H17Cl2N3O3S, MW 402.30 g/mol) for analytical method development and quality control.
The molecular framework of 3,4-Dichloro-N'-(4,6-dimethyl-3-(methylsulfonyl)pyridin-2-yl)-N'-methylbenzohydrazide (C16H17Cl2N3O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
