Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 479.53 g/mol gives (S)-(-)-Nicardipine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (S)-(-)-Nicardipine (CAS 76093-36-2), a certified reference material (molecular formula C26H29N3O6, MW 479.53 g/mol) for analytical method development and quality control.
(S)-(-)-Nicardipine (C26H29N3O6) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
