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 (αE)-5-Bromo-α-[(5-bromo-2-thienyl)methylene]-2-thiopheneacetonitrile (CAS 439588-79-1), a certified reference material (molecular formula C11H5Br2NS2, MW 375.10 g/mol) for analytical method development and quality control.
(αE)-5-Bromo-α-[(5-bromo-2-thienyl)methylene]-2-thiopheneacetonitrile (C11H5Br2NS2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
