Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 350.41 g/mol gives Cbz-Leu-Abu-OH distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cbz-Leu-Abu-OH (CAS 144249-05-8), a certified reference material (molecular formula C18H26N2O5, MW 350.41 g/mol) for analytical method development and quality control.
The molecular framework of Cbz-Leu-Abu-OH (C18H26N2O5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures Cbz-Leu-Abu-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.
