Chemical Structure
Description
5-(Benzo[d]oxazol-2-yl)benzene-1,3-diamine (CAS 56629-40-4) is a high-purity analytical reference standard with the molecular formula C13H11N3O and a molecular weight of 225.25 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 5-(Benzo[d]oxazol-2-yl)benzene-1,3-diamine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 225.25 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 5-(Benzo[d]oxazol-2-yl)benzene-1,3-diamine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
