Chemical Structure
Description
11-trans Leukotriene E4 (CAS 75715-88-7), molecular formula C23H37NO5S and molecular weight 439.61 g/mol, is a CATO reference standard with documented purity and traceability.
11-trans Leukotriene E4 (C23H37NO5S) contains a steroid core, an amide group, a sulfone group, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 11-trans Leukotriene E4 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
