Chemical Structure
Description
The molecular framework of (±)-Nisoldipine-d4 (2-nitrophenyl-d4) (C20H20D4N2O6) is characterized by deuterium isotope labeling, a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies (±)-Nisoldipine-d4 (2-nitrophenyl-d4) (CAS 1219795-47-7), a certified reference material (molecular formula C20H20D4N2O6, MW 392.44 g/mol) for analytical method development and quality control.
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), (±)-Nisoldipine-d4 (2-nitrophenyl-d4) 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.
