Compared with other compounds in its class, the molecular weight of 233.24 g/mol gives Dopamine 3-O-Sulfate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dopamine 3-O-Sulfate (CAS 51317-41-0), a certified reference material (molecular formula C8H11NO5S, MW 233.24 g/mol) for analytical method development and quality control.
Dopamine 3-O-Sulfate (C8H11NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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), Dopamine 3-O-Sulfate 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.
