Chemical Structure

H-Val-Leu-OH · HCl CAS 95977-55-2 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 H-Val-Leu-OH · HCl (CAS 95977-55-2), a certified reference material (molecular formula C11H22N2O3HCl, MW 266.77 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, H-Val-Leu-OH · HCl is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.77 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.

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.
