Chemical Structure
Description
The occurrence of 1-Amino-3-hydroxycyclobutanecarboxylic acid hydrochloride is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Amino-3-hydroxycyclobutanecarboxylic acid hydrochloride (CAS 1246746-62-2), a certified reference material (molecular formula C5H9NO3HCl, MW 167.59 g/mol) for analytical method development and quality control.
The molecular framework of 1-Amino-3-hydroxycyclobutanecarboxylic acid hydrochloride (C5H9NO3HCl) 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.
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.
