Chemical Structure

Z-Tyr(Bzl)-OH CAS 16677-29-5 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies Z-Tyr(Bzl)-OH (CAS 16677-29-5), a certified reference material (molecular formula C24H23NO5, MW 405.45 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Z-Tyr(Bzl)-OH is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
