Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 343.37 g/mol gives Z-Thr-OBzl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Z-Thr-OBzl (CAS 16597-50-5), a certified reference material (molecular formula C19H21NO5, MW 343.37 g/mol) for analytical method development and quality control.
Z-Thr-OBzl (C19H21NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures Z-Thr-OBzl 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.
