The occurrence of Sodium 2-amino-5-nitrobenzenesulfonate is closely related to a carbohydrate-derived structure, an amide group, a sulfone group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sodium 2-amino-5-nitrobenzenesulfonate (CAS 30693-53-9) is a high-purity analytical reference standard with the molecular formula C6H5N2O5SNa and a molecular weight of 240.17 g/mol.
Owing to a carbohydrate-derived structure, an amide group, a sulfone group, Sodium 2-amino-5-nitrobenzenesulfonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Sodium 2-amino-5-nitrobenzenesulfonate 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.
