Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 336.91 g/mol gives Methdilazine-d4 Hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Methdilazine-d4 Hydrochloride (CAS 1330055-82-7), molecular formula C18H16D4N2SHCl and molecular weight 336.91 g/mol, is a CATO reference standard with documented purity and traceability.
Methdilazine-d4 Hydrochloride (C18H16D4N2SHCl) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), Methdilazine-d4 Hydrochloride 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.
