Chemical Structure

1-(4-Butylphenyl)-4-(5,5-dimethyl-1,3-dioxan-2-yl)butan-1-one CAS 898787-25-2 chemical structure

Description

The occurrence of 1-(4-Butylphenyl)-4-(5,5-dimethyl-1,3-dioxan-2-yl)butan-1-one is closely related to a steroid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(4-Butylphenyl)-4-(5,5-dimethyl-1,3-dioxan-2-yl)butan-1-one (CAS 898787-25-2) is a high-purity analytical reference standard with the molecular formula C20H30O3 and a molecular weight of 318.45 g/mol.

The molecular framework of 1-(4-Butylphenyl)-4-(5,5-dimethyl-1,3-dioxan-2-yl)butan-1-one (C20H30O3) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
