4-Methoxy-N-(thieno[2,3-d]pyrimidin-4-yl)benzamide CAS 1004052-50-9

Description

The occurrence of 4-Methoxy-N-(thieno[2,3-d]pyrimidin-4-yl)benzamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Methoxy-N-(thieno[2,3-d]pyrimidin-4-yl)benzamide (CAS 1004052-50-9), a certified reference material (molecular formula C14H11N3O2S, MW 285.32 g/mol) for analytical method development and quality control.

Based on its molecular formula C14H11N3O2S, 4-Methoxy-N-(thieno[2,3-d]pyrimidin-4-yl)benzamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
