Chemical Structure
Description
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.
Disodium 8-Amino-1,3,6-naphthalenetrisulfonate (CAS 5398-34-5) is a high-purity analytical reference standard with the molecular formula C10H7NO9S3Na and a molecular weight of 404.33 g/mol.
Disodium 8-Amino-1,3,6-naphthalenetrisulfonate (C10H7NO9S3Na) contains a carbohydrate-derived structure, an amide group, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Disodium 8-Amino-1,3,6-naphthalenetrisulfonate 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.
