Chemical Structure
Description
tert-Butyl 4-(5-((6-chloro-4-(methoxycarbonyl)pyridin-2-yl)oxy)pyrimidin-2-yl)piperazine-1-carboxylate (CAS 2007908-94-1) is a high-purity analytical reference standard with the molecular formula C20H24ClN5O5 and a molecular weight of 449.89 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, tert-Butyl 4-(5-((6-chloro-4-(methoxycarbonyl)pyridin-2-yl)oxy)pyrimidin-2-yl)piperazine-1-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 449.89 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
