Chemical Structure

Z-Leu-Ile-OH CAS 42537-96-2 chemical structure

Description

As a certified reference material (CRM), Z-Leu-Ile-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.

Z-Leu-Ile-OH (CAS 42537-96-2) is a high-purity analytical reference standard with the molecular formula C20H30N2O5 and a molecular weight of 378.46 g/mol.

Z-Leu-Ile-OH (C20H30N2O5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
