6263-83-8 EO7HSL24EN 1,3-Dibenzoylpropane 1,5-Pentanedione, 1,5-diphenyl- 1,5-Diphenyl-1,5-pentadione 1,5-Diphenyl-1,5-pentanedione NSC 46678 UNII-EO7HSL24EN CAS 6263-83-8

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, 6263-83-8 EO7HSL24EN 1,3-Dibenzoylpropane 1,5-Pentanedione, 1,5-diphenyl- 1,5-Diphenyl-1,5-pentadione 1,5-Diphenyl-1,5-pentanedione NSC 46678 UNII-EO7HSL24EN is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

6263-83-8 EO7HSL24EN 1,3-Dibenzoylpropane 1,5-Pentanedione, 1,5-diphenyl- 1,5-Diphenyl-1,5-pentadione 1,5-Diphenyl-1,5-pentanedione NSC 46678 UNII-EO7HSL24EN (CAS 6263-83-8) is a high-purity analytical reference standard with the molecular formula C17H28O2 and a molecular weight of 264.40 g/mol.

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.
