Chemical Structure

Butyl acetyl-L-leucyl-L-leucinate CAS 55712-43-1 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 Butyl acetyl-L-leucyl-L-leucinate (CAS 55712-43-1), a certified reference material (molecular formula C18H34N2O4, MW 342.47 g/mol) for analytical method development and quality control.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Butyl acetyl-L-leucyl-L-leucinate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.47 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

As a certified reference material (CRM), Butyl acetyl-L-leucyl-L-leucinate 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.
