Description
CATO manufactures 4-Chloro-2,6,7-trimethyl-5,6,7,8-tetrahydroquinazoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
4-Chloro-2,6,7-trimethyl-5,6,7,8-tetrahydroquinazoline (CAS 1935593-03-5) is a high-purity analytical reference standard with the molecular formula C11H15ClN2 and a molecular weight of 210.70 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 4-Chloro-2,6,7-trimethyl-5,6,7,8-tetrahydroquinazoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 210.70 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
