Chemical Structure
Description
As a certified reference material (CRM), 7,7-Difluoro-2-(methylthio)-6,7-dihydro-3H-cyclopenta[d]pyrimidin-4(5H)-one 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.
CATO supplies 7,7-Difluoro-2-(methylthio)-6,7-dihydro-3H-cyclopenta[d]pyrimidin-4(5H)-one (CAS 1644414-74-3), a certified reference material (molecular formula C8H8F2N2OS, MW 218.22 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, 7,7-Difluoro-2-(methylthio)-6,7-dihydro-3H-cyclopenta[d]pyrimidin-4(5H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 218.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
