30788-51-3 CAS 30788-51-3 chemical structure

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.

13-Ethyl-3-hydroxy-1,3,5,7,9-gonapenten-17-one 30788-51-3 (CAS 30788-51-3) is a high-purity analytical reference standard with the molecular formula C19H20O2 and a molecular weight of 280.36 g/mol.

Based on its molecular formula C19H20O2, 13-Ethyl-3-hydroxy-1,3,5,7,9-gonapenten-17-one 30788-51-3 contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 280.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
