2-{5,6-dimethyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidin-2-yl}acetonitrile CAS 726151-97-9

Description

The occurrence of 2-{5,6-dimethyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidin-2-yl}acetonitrile is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-{5,6-dimethyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidin-2-yl}acetonitrile (CAS 726151-97-9) is a high-purity analytical reference standard with the molecular formula C10H9N3OS and a molecular weight of 219.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-{5,6-dimethyl-4-oxo-3H,4H-thieno[2,3-d]pyrimidin-2-yl}acetonitrile is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
