Chemical Structure
Description
2-Chloro-7-iodo-6-methylthieno[3,2-d]pyrimidine (CAS 2033057-22-4) is a high-purity analytical reference standard with the molecular formula C7H4ClIN2S and a molecular weight of 310.54 g/mol.
The molecular framework of 2-Chloro-7-iodo-6-methylthieno[3,2-d]pyrimidine (C7H4ClIN2S) is characterized by a nitrile group, sulfur-containing functionality, chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Chloro-7-iodo-6-methylthieno[3,2-d]pyrimidine 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.
