Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 350.45 g/mol gives Prostaglandin E3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Prostaglandin E3 (CAS 802-31-3), a certified reference material (molecular formula C20H30O5, MW 350.45 g/mol) for analytical method development and quality control.
Prostaglandin E3 (C20H30O5) contains a steroid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
