Chemical Structure
Description
Structurally, S-(-)-Warfarin-d5 (C19H11D5O4) contains deuterium isotope labeling, a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 313.36 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
S-(-)-Warfarin-d5 (CAS 791013-22-4) is a high-purity analytical reference standard with the molecular formula C19H11D5O4 and a molecular weight of 313.36 g/mol.
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), S-(-)-Warfarin-d5 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.
