Chemical Structure

N,N-Dimethyl-4-(2-phenyl-5,6-dihydro-1,4-oxathiin-3-yl)aniline CAS 156574-52-6 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 N,N-Dimethyl-4-(2-phenyl-5,6-dihydro-1,4-oxathiin-3-yl)aniline (CAS 156574-52-6), a certified reference material (molecular formula C18H19NOS, MW 297.41 g/mol) for analytical method development and quality control.

Structurally, N,N-Dimethyl-4-(2-phenyl-5,6-dihydro-1,4-oxathiin-3-yl)aniline (C18H19NOS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 297.41 g/mol, it falls into the medium-molecular-weight range. 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.
