Chemical Structure

9,11-methane-epoxy Prostaglandin 1α CAS 72517-81-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,11-methane-epoxy Prostaglandin 1α.

9,11-methane-epoxy Prostaglandin 1α (CAS 72517-81-8), molecular formula C21H36O4 and molecular weight 352.51 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, a hydroxyl group, an ether linkage, 9,11-methane-epoxy Prostaglandin 1α is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
