Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 2-[(E)-2-(2,5-Dimethylphenyl)ethenyl]-5-methyl-1,3,4-oxadiazole is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 214.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-[(E)-2-(2,5-Dimethylphenyl)ethenyl]-5-methyl-1,3,4-oxadiazole (CAS 477856-53-4), molecular formula C13H14N2O and molecular weight 214.26 g/mol, is a CATO reference standard with documented purity and traceability.
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.
