(2S,3R,4S)-4-Hydroxyisoleucine CAS 55399-93-4 chemical structure

Description

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.

CATO supplies (2S,3R,4S)-4-Hydroxyisoleucine (CAS 55399-93-4), a certified reference material (molecular formula C6H13NO3, MW 147.17 g/mol) for analytical method development and quality control.

(2S,3R,4S)-4-Hydroxyisoleucine (C6H13NO3) 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.

As a certified reference material (CRM), (2S,3R,4S)-4-Hydroxyisoleucine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
