Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 649.60 g/mol gives Solvent Blue 37 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Solvent Blue 37 (CAS 12226-74-3) is a high-purity analytical reference standard with the molecular formula C26H16N3O10S3Na and a molecular weight of 649.60 g/mol.
Solvent Blue 37 (C26H16N3O10S3Na) 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), Solvent Blue 37 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.
