Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Eprosartan Dimethyl Ester.
Eprosartan Dimethyl Ester (CAS 133040-06-9) is a high-purity analytical reference standard with the molecular formula C25H28N2O4S and a molecular weight of 452.57 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Eprosartan Dimethyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 452.57 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Eprosartan Dimethyl Ester 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.
