Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

3-(3-Hydroxy-4-methoxyphenyl)-1-(naphthalen-2-yl)prop-2-en-1-one (CAS 944443-38-3), molecular formula C20H16O3 and molecular weight 304.34 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(3-Hydroxy-4-methoxyphenyl)-1-(naphthalen-2-yl)prop-2-en-1-one (C20H16O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 304.34 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).

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.
