7,9-Dimethylpyrido[3',2':4,5]furo[3,2-d]pyrimidine-4(3H)-thione CAS 1144455-32-2

Description

CATO manufactures 7,9-Dimethylpyrido[3',2':4,5]furo[3,2-d]pyrimidine-4(3H)-thione 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.

7,9-Dimethylpyrido[3',2':4,5]furo[3,2-d]pyrimidine-4(3H)-thione (CAS 1144455-32-2), molecular formula C11H9N3OS and molecular weight 231.27 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 7,9-Dimethylpyrido[3',2':4,5]furo[3,2-d]pyrimidine-4(3H)-thione is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 231.27 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.
