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 1-(2,3-Dimethylphenyl)-3-(3,4-dimethylphenyl)propan-1-one (CAS 898779-32-3), a certified reference material (molecular formula C19H22O, MW 266.38 g/mol) for analytical method development and quality control.
Structurally, 1-(2,3-Dimethylphenyl)-3-(3,4-dimethylphenyl)propan-1-one (C19H22O) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 266.38 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.
