Chemical Structure
Description
As a certified reference material (CRM), 1,3,5-Naphthalenetrisulfonic Acid 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.
1,3,5-Naphthalenetrisulfonic Acid (CAS 6654-64-4) is a high-purity analytical reference standard with the molecular formula C10H8O9S3 and a molecular weight of 368.36 g/mol.
1,3,5-Naphthalenetrisulfonic Acid (C10H8O9S3) contains a carbohydrate-derived structure, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
