Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 340.46 g/mol gives trans-Dihydro Lisuride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
trans-Dihydro Lisuride (CAS 37686-84-3), molecular formula C20H28N4O and molecular weight 340.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of trans-Dihydro Lisuride (C20H28N4O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), trans-Dihydro Lisuride 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.
