Chemical Structure

6-Methyl-2-oxo-4-sulfanylidene-1H-pyrimidine-5-carbonitrile CAS 2228-22-0 chemical structure

Description

CATO manufactures 6-Methyl-2-oxo-4-sulfanylidene-1H-pyrimidine-5-carbonitrile 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.

6-Methyl-2-oxo-4-sulfanylidene-1H-pyrimidine-5-carbonitrile (CAS 2228-22-0), molecular formula C6H5N3OS and molecular weight 167.19 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 6-Methyl-2-oxo-4-sulfanylidene-1H-pyrimidine-5-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 167.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
