Compared with other compounds in its class, the molecular weight of 274.21 g/mol gives 4-(Pentafluorosulfur)cinnamic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-(Pentafluorosulfur)cinnamic acid (CAS 1240261-80-6), a certified reference material (molecular formula C9H7F5O2S, MW 274.21 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-(Pentafluorosulfur)cinnamic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 274.21 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).
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), 4-(Pentafluorosulfur)cinnamic acid 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.
