Chemical Structure
Description
(S)-Rasagiline Esilate (CAS 202464-89-9), molecular formula C12H13NC2H6O3S and molecular weight 281.37 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-Rasagiline Esilate (C12H13NC2H6O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), (S)-Rasagiline Esilate 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.
