Chemical Structure

Z-Leu-Leu-OH CAS 7801-71-0 chemical structure

Description

The occurrence of Z-Leu-Leu-OH is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Z-Leu-Leu-OH (CAS 7801-71-0) is a high-purity analytical reference standard with the molecular formula C20H30N2O5 and a molecular weight of 378.46 g/mol.

Z-Leu-Leu-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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 manufactures Z-Leu-Leu-OH under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
