Chemical Structure
Description
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.
1-(5-Cyano-2-methylphenyl)-3-cyclopentylurea (CAS 1333692-82-2), molecular formula C14H17N3O and molecular weight 243.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(5-Cyano-2-methylphenyl)-3-cyclopentylurea is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 243.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
