5-(Benzo[d]oxazol-2-yl)-2-chloroaniline CAS 313701-55-2

Description

Compared with other compounds in its class, the molecular weight of 244.68 g/mol gives 5-(Benzo[d]oxazol-2-yl)-2-chloroaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-(Benzo[d]oxazol-2-yl)-2-chloroaniline (CAS 313701-55-2), molecular formula C13H9ClN2O and molecular weight 244.68 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, chlorine substitution, 5-(Benzo[d]oxazol-2-yl)-2-chloroaniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 244.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
