Chemical Structure

5-Phenyl-5-ethyl-d CAS 73738-04-2 chemical structure

Description

CATO supplies 5-Phenyl-5-ethyl-d (CAS 73738-04-2), a certified reference material (molecular formula C12H7D5N2O2S, MW 253.33 g/mol) for analytical method development and quality control.

Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 5-Phenyl-5-ethyl-d is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 253.33 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).

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

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.
