Description

Compared with other compounds in its class, the molecular weight of 243.30 g/mol gives cis-2-((tert-Butoxycarbonyl)amino)cyclohexanecarboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies cis-2-((tert-Butoxycarbonyl)amino)cyclohexanecarboxylic acid (CAS 63216-49-9), a certified reference material (molecular formula C12H21NO4, MW 243.30 g/mol) for analytical method development and quality control.

cis-2-((tert-Butoxycarbonyl)amino)cyclohexanecarboxylic acid (C12H21NO4) contains an amino-acid-derived structure, an amide 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.
