Chemical Structure
Description
The occurrence of rac Clopidogrel-13C,d3 Hydrogen Sulfate is closely related to deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
rac Clopidogrel-13C,d3 Hydrogen Sulfate (CAS 1246814-55-0) is a high-purity analytical reference standard with the molecular formula C15[13C]H13D3ClNO2S H2O4S and a molecular weight of 422.91 g/mol.
Structurally, rac Clopidogrel-13C,d3 Hydrogen Sulfate (C15[13C]H13D3ClNO2S H2O4S) contains deuterium isotope labeling, a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.5, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 422.91 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
