Description
CATO supplies 7-Iodo-2-methylthieno[3,2-d]pyrimidin-4-ol (CAS 1823542-87-5), a certified reference material (molecular formula C7H5IN2OS, MW 292.10 g/mol) for analytical method development and quality control.
7-Iodo-2-methylthieno[3,2-d]pyrimidin-4-ol (C7H5IN2OS) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), 7-Iodo-2-methylthieno[3,2-d]pyrimidin-4-ol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
