Chemical Structure
Description
Structurally, Ethyl 8-(2,3,4-trimethoxyphenyl)-8-oxooctanoate (C19H28O6) contains a steroid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 352.42 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).
Ethyl 8-(2,3,4-trimethoxyphenyl)-8-oxooctanoate (CAS 951888-66-7) is a high-purity analytical reference standard with the molecular formula C19H28O6 and a molecular weight of 352.42 g/mol.
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.
