Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 318.28 g/mol gives Dantrolene-d4 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dantrolene-d4 (CAS 7261-97-4 (unlabeled)), a certified reference material (molecular formula C14H6D4N4O5, MW 318.28 g/mol) for analytical method development and quality control.
Dantrolene-d4 (C14H6D4N4O5) contains deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, 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.
As a certified reference material (CRM), Dantrolene-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.
