Chemical Structure
Description
CATO supplies n-(2-((5,6-Dimethylthieno[2,3-d]pyrimidin-4-yl)amino)ethyl)acetamide (CAS 851721-39-6), a certified reference material (molecular formula C12H16N4OS, MW 264.35 g/mol) for analytical method development and quality control.
n-(2-((5,6-Dimethylthieno[2,3-d]pyrimidin-4-yl)amino)ethyl)acetamide (C12H16N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; 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.
