Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 219.10 g/mol gives 3-(4-Bromothiophen-2-yl)propanal distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(4-Bromothiophen-2-yl)propanal (CAS 1247380-57-9), molecular formula C7H7BrOS and molecular weight 219.10 g/mol, is a CATO reference standard with documented purity and traceability.
3-(4-Bromothiophen-2-yl)propanal (C7H7BrOS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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).
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.
