Chemical Structure
Description
8-Aminonaphthalene-1,3,5-trisulfonic acid sodium salt(1:x) (CAS 94349-55-0) is a high-purity analytical reference standard with the molecular formula C10H8NO9S3Na and a molecular weight of 405.34 g/mol.
The molecular framework of 8-Aminonaphthalene-1,3,5-trisulfonic acid sodium salt(1:x) (C10H8NO9S3Na) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 8-Aminonaphthalene-1,3,5-trisulfonic acid sodium salt(1:x) 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.
