Chemical Structure

2,6-Di-tert-butyl-4-methylphenol D21 CAS 64502-99-4 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 2,6-Di-tert-butyl-4-methylphenol D21 (CAS 64502-99-4), a certified reference material (molecular formula C15H3D21O, MW 241.48 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a hydroxyl group, an ether linkage, a polycyclic aromatic system, 2,6-Di-tert-butyl-4-methylphenol D21 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 241.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
