Chemical Structure
Description
4-(Naphthalen-2-yloxy)thieno[2,3-d]pyrimidine (CAS 683780-01-0), molecular formula C16H10N2OS and molecular weight 278.33 g/mol, is a CATO reference standard with documented purity and traceability.
4-(Naphthalen-2-yloxy)thieno[2,3-d]pyrimidine (C16H10N2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
