Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-((4,6-Dichloro-1,3,5-triazin-2-yl)amino)benzenesulfonic acid.
CATO supplies 2-((4,6-Dichloro-1,3,5-triazin-2-yl)amino)benzenesulfonic acid (CAS 86964-20-7), a certified reference material (molecular formula C9H6Cl2N4O3S, MW 321.14 g/mol) for analytical method development and quality control.
Structurally, 2-((4,6-Dichloro-1,3,5-triazin-2-yl)amino)benzenesulfonic acid (C9H6Cl2N4O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 321.14 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
