Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,3,6-naphthalenetrisulfonic acid 86-66-8 CHEBI:32916 naphthalene-1,3,6-trisulfonic acid naphthalene-1,3,6-trisulphonic acid.
CATO supplies 1,3,6-naphthalenetrisulfonic acid 86-66-8 CHEBI:32916 naphthalene-1,3,6-trisulfonic acid naphthalene-1,3,6-trisulphonic acid (CAS 86-66-8), a certified reference material (molecular formula C10H8O9S3, MW 368.36 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H8O9S3, 1,3,6-naphthalenetrisulfonic acid 86-66-8 CHEBI:32916 naphthalene-1,3,6-trisulfonic acid naphthalene-1,3,6-trisulphonic acid contains a carbohydrate-derived structure, a sulfone group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 368.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
