The occurrence of 3-{[(2-methylphenyl)methyl]sulfanyl}-5H,6H-benzo[h]cinnoline is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-{[(2-methylphenyl)methyl]sulfanyl}-5H,6H-benzo[h]cinnoline (CAS 478047-89-1), a certified reference material (molecular formula C20H18N2S, MW 318.44 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 3-{[(2-methylphenyl)methyl]sulfanyl}-5H,6H-benzo[h]cinnoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
