Chemical Structure

N,N,7-trimethylthieno[3,2-d]pyrimidin-4-amine CAS 676546-12-6 chemical structure

Description

Based on its molecular formula C9H11N3S, N,N,7-trimethylthieno[3,2-d]pyrimidin-4-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies N,N,7-trimethylthieno[3,2-d]pyrimidin-4-amine (CAS 676546-12-6), a certified reference material (molecular formula C9H11N3S, MW 193.27 g/mol) for analytical method development and quality control.

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.
