The occurrence of 2-Methylthieno[2,3-D]Pyrimidin-4-Amine is closely related to a nitrile group, sulfur-containing functionality, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2-Methylthieno[2,3-D]Pyrimidin-4-Amine (CAS 60703-75-5), a certified reference material (molecular formula C7H7N3S, MW 165.22 g/mol) for analytical method development and quality control.
The molecular framework of 2-Methylthieno[2,3-D]Pyrimidin-4-Amine (C7H7N3S) is characterized by a nitrile group, sulfur-containing functionality, 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).
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 2-Methylthieno[2,3-D]Pyrimidin-4-Amine 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.
