Chemical Structure

H-Phe(2,4-DiMe)-OH CAS 259726-56-2 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 H-Phe(2,4-DiMe)-OH (CAS 259726-56-2), a certified reference material (molecular formula C11H15NO2, MW 193.24 g/mol) for analytical method development and quality control.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, H-Phe(2,4-DiMe)-OH is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 193.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
