Chemical Structure

H-Val-OBzl · p-tosylate CAS 16652-76-9 chemical structure

Description

H-Val-OBzl · p-tosylate (CAS 16652-76-9) is a high-purity analytical reference standard with the molecular formula C12H17NO2C7H8O3S and a molecular weight of 379.47 g/mol.

The molecular framework of H-Val-OBzl · p-tosylate (C12H17NO2C7H8O3S) is characterized by a flavonoid core, an amide group, a sulfone 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 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 H-Val-OBzl · p-tosylate 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.
