Description
As a certified reference material (CRM), 6-methyl-2-(2-methylphenyl)quinazoline-4-thiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 6-methyl-2-(2-methylphenyl)quinazoline-4-thiol (CAS 1909306-20-2), a certified reference material (molecular formula C16H14N2S, MW 266.36 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 6-methyl-2-(2-methylphenyl)quinazoline-4-thiol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 266.36 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.
