4-Chloro-L-threonine CAS 142698-80-4

Description

Compared with other compounds in its class, the molecular weight of 153.56 g/mol gives 4-Chloro-L-threonine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Chloro-L-threonine (CAS 142698-80-4), a certified reference material (molecular formula C4H8ClNO3, MW 153.56 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 4-Chloro-L-threonine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
