Compared with other compounds in its class, the molecular weight of 246.72 g/mol gives 4-Chloro-6-phenylthieno[3,2-d]pyrimidine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-6-phenylthieno[3,2-d]pyrimidine (CAS 209853-25-8), a certified reference material (molecular formula C12H7ClN2S, MW 246.72 g/mol) for analytical method development and quality control.
The molecular framework of 4-Chloro-6-phenylthieno[3,2-d]pyrimidine (C12H7ClN2S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
CATO manufactures 4-Chloro-6-phenylthieno[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.
