Cyclosporin E CAS 63798-73-2 chemical structure

Description

As a certified reference material (CRM), Cyclosporin E 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.

CATO supplies Cyclosporin E (CAS 63798-73-2), a certified reference material (molecular formula C61H109N11O12, MW 1188.58 g/mol) for analytical method development and quality control.

Cyclosporin E (C61H109N11O12) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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).

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.
