4-Chloro-2-(difluoro(4-fluorophenyl)methyl)thieno[2,3-d]pyrimidine CAS 1362710-33-5

Description

4-Chloro-2-(difluoro(4-fluorophenyl)methyl)thieno[2,3-d]pyrimidine (CAS 1362710-33-5) is a high-purity analytical reference standard with the molecular formula C13H6ClF3N2S and a molecular weight of 314.71 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, 4-Chloro-2-(difluoro(4-fluorophenyl)methyl)thieno[2,3-d]pyrimidine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.71 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.

As a certified reference material (CRM), 4-Chloro-2-(difluoro(4-fluorophenyl)methyl)thieno[2,3-d]pyrimidine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
