Compared with other compounds in its class, the molecular weight of 242.30 g/mol gives 5-(4-Aminophenyl)thieno[2,3-d]pyrimidin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-(4-Aminophenyl)thieno[2,3-d]pyrimidin-4-amine (CAS 501696-28-2), a certified reference material (molecular formula C12H10N4S, MW 242.30 g/mol) for analytical method development and quality control.
5-(4-Aminophenyl)thieno[2,3-d]pyrimidin-4-amine (C12H10N4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
