Chemical Structure

1-(tert-Butoxycarbonyl)-4-ethylpiperidine-2-carboxylic acid CAS 123811-84-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(tert-Butoxycarbonyl)-4-ethylpiperidine-2-carboxylic acid.

1-(tert-Butoxycarbonyl)-4-ethylpiperidine-2-carboxylic acid (CAS 123811-84-7) is a high-purity analytical reference standard with the molecular formula C13H23NO4 and a molecular weight of 257.33 g/mol.

1-(tert-Butoxycarbonyl)-4-ethylpiperidine-2-carboxylic acid (C13H23NO4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
