Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 324.47 g/mol gives Tetrabenazine-d7 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tetrabenazine-d7 (CAS 58-46-8 (unlabelled)) is a high-purity analytical reference standard with the molecular formula C19H20D7NO3 and a molecular weight of 324.47 g/mol.
Tetrabenazine-d7 (C19H20D7NO3) contains deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Tetrabenazine-d7 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.
