Chemical Structure

H-Met-Arg-OH CAS 60461-10-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 305.40 g/mol gives H-Met-Arg-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies H-Met-Arg-OH (CAS 60461-10-1), a certified reference material (molecular formula C11H23N5O3S, MW 305.40 g/mol) for analytical method development and quality control.

Based on its molecular formula C11H23N5O3S, H-Met-Arg-OH contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 305.40 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
