(3-Amino-4,6-dimethylthieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone CAS 295345-20-9

Description

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.

(3-Amino-4,6-dimethylthieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone (CAS 295345-20-9), molecular formula C16H13BrN2OS and molecular weight 361.26 g/mol, is a CATO reference standard with documented purity and traceability.

(3-Amino-4,6-dimethylthieno[2,3-b]pyridin-2-yl)(4-bromophenyl)methanone (C16H13BrN2OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
