Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 6-(tert-Butyl) 3-ethyl 4-hydroxy-2-oxo-1,5,7,8-tetrahydro-1,6-naphthyridine-3,6(2H)-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 338.36 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 6-(tert-Butyl) 3-ethyl 4-hydroxy-2-oxo-1,5,7,8-tetrahydro-1,6-naphthyridine-3,6(2H)-dicarboxylate (CAS 2135936-05-7), a certified reference material (molecular formula C16H22N2O6, MW 338.36 g/mol) for analytical method development and quality control.
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.
