Chemical Structure
Description
2,4,6-Trichlorobenzene-1,3,5-tricarbonitrile (CAS 3638-98-0) is a high-purity analytical reference standard with the molecular formula C9Cl3N3 and a molecular weight of 256.48 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 2,4,6-Trichlorobenzene-1,3,5-tricarbonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
