Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 3-((2-chloropyridin-4-yl)oxy)-6-methylpicolinate.
CATO supplies Methyl 3-((2-chloropyridin-4-yl)oxy)-6-methylpicolinate (CAS 1117684-86-2), a certified reference material (molecular formula C13H11ClN2O3, MW 278.69 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-((2-chloropyridin-4-yl)oxy)-6-methylpicolinate (C13H11ClN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.
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.
