N,N-diethyl-2-(methylthio)thieno[2,3-d]pyrimidin-4-amine CAS 383146-91-6

Description

The occurrence of N,N-diethyl-2-(methylthio)thieno[2,3-d]pyrimidin-4-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N,N-diethyl-2-(methylthio)thieno[2,3-d]pyrimidin-4-amine (CAS 383146-91-6) is a high-purity analytical reference standard with the molecular formula C11H15N3S2 and a molecular weight of 253.39 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, N,N-diethyl-2-(methylthio)thieno[2,3-d]pyrimidin-4-amine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
