Chemical Structure

Ac-p-Bz-D-Phe-OH CAS 104504-42-9 chemical structure

Description

The occurrence of Ac-p-Bz-D-Phe-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.

Ac-p-Bz-D-Phe-OH (CAS 104504-42-9), molecular formula C18H17NO4 and molecular weight 311.33 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C18H17NO4, Ac-p-Bz-D-Phe-OH contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 311.33 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures Ac-p-Bz-D-Phe-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.
