Chemical Structure
Description
The occurrence of rac a-Methadol D3 is closely related to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
rac a-Methadol D3 (CAS 1217842-77-7) is a high-purity analytical reference standard with the molecular formula C21H26D3NO and a molecular weight of 314.48 g/mol.
rac a-Methadol D3 (C21H26D3NO) 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; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), rac a-Methadol D3 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.
