Chemical Structure
Description
The occurrence of (E)-3-(3-chloro-5-(pentafluoro-lambda6-sulfanyl)phenyl)acrylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (E)-3-(3-chloro-5-(pentafluoro-lambda6-sulfanyl)phenyl)acrylic acid (CAS 1240261-79-3), a certified reference material (molecular formula C9H6ClF5O2S, MW 308.65 g/mol) for analytical method development and quality control.
(E)-3-(3-chloro-5-(pentafluoro-lambda6-sulfanyl)phenyl)acrylic acid (C9H6ClF5O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
