Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Fluoro-2-(methylthio)benzaldehyde.
CATO supplies 5-Fluoro-2-(methylthio)benzaldehyde (CAS 160503-79-7), a certified reference material (molecular formula C8H7FOS, MW 170.20 g/mol) for analytical method development and quality control.
The molecular framework of 5-Fluoro-2-(methylthio)benzaldehyde (C8H7FOS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
