Chemical Structure
Description
The occurrence of 2-Fluoro-4-methyl-6-(methylthio)benzaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Fluoro-4-methyl-6-(methylthio)benzaldehyde (CAS 2092789-64-3), molecular formula C9H9FOS and molecular weight 184.23 g/mol, is a CATO reference standard with documented purity and traceability.
2-Fluoro-4-methyl-6-(methylthio)benzaldehyde (C9H9FOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Fluoro-4-methyl-6-(methylthio)benzaldehyde 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.
