Chemical Structure
Description
CATO supplies 3-(Benzo[d]thiazol-2-yl)-4-chloroaniline (CAS 292644-36-1), a certified reference material (molecular formula C13H9ClN2S, MW 260.74 g/mol) for analytical method development and quality control.
3-(Benzo[d]thiazol-2-yl)-4-chloroaniline (C13H9ClN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
