Chemical Structure
Description
Tert-butyl 4-(5-(ethoxycarbonyl)pyridin-2-yl)piperazine-1-carboxylate (CAS 201809-20-3) is a high-purity analytical reference standard with the molecular formula C17H25N3O4 and a molecular weight of 335.40 g/mol.
The molecular framework of Tert-butyl 4-(5-(ethoxycarbonyl)pyridin-2-yl)piperazine-1-carboxylate (C17H25N3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
