Chemical Structure

Ac-Arg-OH CAS 155-84-0 chemical structure

Description

As a certified reference material (CRM), Ac-Arg-OH 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.

CATO supplies Ac-Arg-OH (CAS 155-84-0), a certified reference material (molecular formula C8H16N4O3, MW 216.24 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ac-Arg-OH is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 216.24 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.

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.
