Chemical Structure
Description
Dihydro Ergotamine-13C,d3 Mesylate (CAS 1356841-81-0), molecular formula C32[13C]H34D3N5O5 CH4O3S and molecular weight 682.81 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C32[13C]H34D3N5O5 CH4O3S, Dihydro Ergotamine-13C,d3 Mesylate contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 682.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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), Dihydro Ergotamine-13C,d3 Mesylate 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.
