Chemical Structure

Ac-Ile-OH CAS 3077-46-1 chemical structure

Description

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ac-Ile-OH is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Ac-Ile-OH (CAS 3077-46-1), molecular formula C8H15NO3 and molecular weight 173.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.
