Chemical Structure
Description
CATO supplies 1,3-Bis(1,1-dimethylethyl) 2-(2-chloro-3-pyridinyl)imidodicarbonate (CAS 749265-07-4), a certified reference material (molecular formula C15H21ClN2O4, MW 328.79 g/mol) for analytical method development and quality control.
1,3-Bis(1,1-dimethylethyl) 2-(2-chloro-3-pyridinyl)imidodicarbonate (C15H21ClN2O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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.
