1-(Anthracen-9-yl)-5-(5,5-dimethyl-1,3-dioxan-2-yl)pentan-1-one CAS 898757-53-4

Description

1-(Anthracen-9-yl)-5-(5,5-dimethyl-1,3-dioxan-2-yl)pentan-1-one (CAS 898757-53-4), molecular formula C25H28O3 and molecular weight 376.49 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(Anthracen-9-yl)-5-(5,5-dimethyl-1,3-dioxan-2-yl)pentan-1-one (C25H28O3) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 376.49 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).

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.

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.
