Chemical Structure
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.
4-[5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl -piperazine-1-carboxylic acid tert-butyl ester 4-[5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-2-yl]-piperazine-1-carboxylic acid tert-butyl ester 496786-98-2 6-[4-(tert-Butoxycarbonyl)piperazin-1-yl]pyridine-3-boronic acid, pinacol ester 97% tert-Butyl 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl]piperazine-1-carboxylate tert-butyl 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-pyridinyl]tetrahydro-1(2H)-pyrazinecarboxylate (CAS 496786-98-2) is a high-purity analytical reference standard with the molecular formula C20H38BN3O4 and a molecular weight of 395.34 g/mol.
The molecular framework of 4-[5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl -piperazine-1-carboxylic acid tert-butyl ester 4-[5-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-pyridin-2-yl]-piperazine-1-carboxylic acid tert-butyl ester 496786-98-2 6-[4-(tert-Butoxycarbonyl)piperazin-1-yl]pyridine-3-boronic acid, pinacol ester 97% tert-Butyl 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridin-2-yl]piperazine-1-carboxylate tert-butyl 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-pyridinyl]tetrahydro-1(2H)-pyrazinecarboxylate (C20H38BN3O4) is characterized by an amide group, a carboxylic acid 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
