Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 120681-05-2 2-Propenoyl chloride, 3-(2-fluorophenyl)-, (2E)- ACMC-20mp29 (CAS 120681-05-2), a certified reference material (molecular formula C9H6ClFO, MW 184.59 g/mol) for analytical method development and quality control.
120681-05-2 2-Propenoyl chloride, 3-(2-fluorophenyl)-, (2E)- ACMC-20mp29 (C9H6ClFO) contains a hydroxyl group, an ether linkage, fluorine/chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
