2-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}ethane-1-sulfonyl fluoride CAS 877964-12-0 chemical structure

Description

The occurrence of 2-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}ethane-1-sulfonyl fluoride is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}ethane-1-sulfonyl fluoride (CAS 877964-12-0), molecular formula C8H13FN2O3S2 and molecular weight 268.33 g/mol, is a CATO reference standard with documented purity and traceability.

2-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}ethane-1-sulfonyl fluoride (C8H13FN2O3S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures 2-{4-oxo-3H,4H-thieno[2,3-d]pyrimidin-3-yl}ethane-1-sulfonyl fluoride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
