5-bromo-2,4-dimethoxy-thieno[2,3-d]pyrimidine CAS 2659313-23-0

Description

The occurrence of 5-bromo-2,4-dimethoxy-thieno[2,3-d]pyrimidine is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-bromo-2,4-dimethoxy-thieno[2,3-d]pyrimidine (CAS 2659313-23-0), a certified reference material (molecular formula C8H15BrN2O2S, MW 283.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H15BrN2O2S, 5-bromo-2,4-dimethoxy-thieno[2,3-d]pyrimidine contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 283.19 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.
