Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 352.38 g/mol gives Travoprost Impurity 50 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Travoprost Impurity 50 (CAS 2218532-68-2) is a certified pharmaceutical impurity reference standard with the molecular formula C21H20O5 and a molecular weight of 352.38 g/mol.
Structurally, Travoprost Impurity 50 (C21H20O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 352.38 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
As a certified reference material (CRM), Travoprost Impurity 50 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.
