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 3-((tert-Butoxycarbonyl)amino)-2,6-dichloroisonicotinic acid.
3-((tert-Butoxycarbonyl)amino)-2,6-dichloroisonicotinic acid (CAS 1956379-65-9) is a high-purity analytical reference standard with the molecular formula C11H12Cl2N2O4 and a molecular weight of 307.13 g/mol.
The molecular framework of 3-((tert-Butoxycarbonyl)amino)-2,6-dichloroisonicotinic acid (C11H12Cl2N2O4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
