Chemical Structure

Ethyl (1S,3R,4R)-4-{[(tert-butoxy)carbonyl]amino}-3-hydroxycyclohexane-1-carboxylate hydrochloride CAS 1403763-28-9 chemical structure

Description

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.

CATO supplies Ethyl (1S,3R,4R)-4-{[(tert-butoxy)carbonyl]amino}-3-hydroxycyclohexane-1-carboxylate hydrochloride (CAS 1403763-28-9), a certified reference material (molecular formula C14H25NO5HCl, MW 323.81 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl (1S,3R,4R)-4-{[(tert-butoxy)carbonyl]amino}-3-hydroxycyclohexane-1-carboxylate hydrochloride (C14H25NO5HCl) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
