Chemical Structure

76822-56-5 Prost-13-en-1-oic acid, 11,15-dihydroxy-16-methoxy-16-methyl-9-oxo-, methyl ester, (11alpha,13E,15R,16R)- MDL 646 (16R)-Mexiprostil CAS 76822-56-5 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.

76822-56-5 Prost-13-en-1-oic acid, 11,15-dihydroxy-16-methoxy-16-methyl-9-oxo-, methyl ester, (11alpha,13E,15R,16R)- MDL 646 (16R)-Mexiprostil (CAS 76822-56-5) is a high-purity analytical reference standard with the molecular formula C23H40O6 and a molecular weight of 412.56 g/mol.

The molecular framework of 76822-56-5 Prost-13-en-1-oic acid, 11,15-dihydroxy-16-methoxy-16-methyl-9-oxo-, methyl ester, (11alpha,13E,15R,16R)- MDL 646 (16R)-Mexiprostil (C23H40O6) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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).

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.
