(5Z,13E)-9alpha,11alpha-dihydroxy-15-oxoprosta-5,13-dien-1-oic acid 15-Keto-PGF2a 15-Keto-PGF2alpha 15-Keto-prostaglandin F2a 15-Keto-prostaglandin F2alpha 15-Ketoprostaglandin F2alpha 15-oxoprostaglandin F2alpha 35850-13-6 CHEBI:28442 (C20H32O5) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
