Chemical Structure

H-Met-Ile-OH CAS 40883-17-8 chemical structure

Description

CATO supplies H-Met-Ile-OH (CAS 40883-17-8), a certified reference material (molecular formula C11H22N2O3S, MW 262.37 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H22N2O3S, H-Met-Ile-OH contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 262.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
