Description
CATO manufactures 4-Chloro-6-iodo-5-methylthieno[2,3-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.
CATO supplies 4-Chloro-6-iodo-5-methylthieno[2,3-d]pyrimidine (CAS 1823372-30-0), a certified reference material (molecular formula C7H4ClIN2S, MW 310.54 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-6-iodo-5-methylthieno[2,3-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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
