Chemical Structure

Tapinarof D5 CAS CATO-C4X-244510 chemical structure

Description

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.

CATO supplies Tapinarof D5 (CAS CATO-C4X-244510), a certified reference material (molecular formula C17H13D5O2, MW 259.35 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a steroid core, a hydroxyl group, an ether linkage, Tapinarof D5 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.35 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).

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