Compared with other compounds in its class, the molecular weight of 542.03 g/mol gives (3S,4'R)-Benidipine HCl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(3S,4'R)-Benidipine HCl (CAS 119009-45-9) is a high-purity analytical reference standard with the molecular formula C28H31N3O6HCl and a molecular weight of 542.03 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (3S,4'R)-Benidipine HCl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 542.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), (3S,4'R)-Benidipine HCl 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.
