Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 433.92 g/mol gives Clopidogrel Ethyl Ester Sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Clopidogrel Ethyl Ester Sulfate (CAS 1332612-57-3), a certified reference material (molecular formula C17H18ClNO2SH2O4S, MW 433.92 g/mol) for analytical method development and quality control.
Structurally, Clopidogrel Ethyl Ester Sulfate (C17H18ClNO2SH2O4S) contains 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 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 433.92 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
CATO manufactures Clopidogrel Ethyl Ester Sulfate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
