6-(4-(Tert-butoxycarbonyl)piperazin-1-yl)-5-chloronicotinic acid CAS 683241-92-1

Description

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.

6-(4-(Tert-butoxycarbonyl)piperazin-1-yl)-5-chloronicotinic acid (CAS 683241-92-1) is a high-purity analytical reference standard with the molecular formula C15H20ClN3O4 and a molecular weight of 341.79 g/mol.

6-(4-(Tert-butoxycarbonyl)piperazin-1-yl)-5-chloronicotinic acid (C15H20ClN3O4) contains a flavonoid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
