Chemical Structure
Description
3-(2,3-Dimethylphenoxy)-2-phenylquinoline-4-carboxylic acid (CAS 400079-73-4), molecular formula C24H19NO3 and molecular weight 369.41 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(2,3-Dimethylphenoxy)-2-phenylquinoline-4-carboxylic acid (C24H19NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 369.41 g/mol, it falls into the moderately-high-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.
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.
