6-Chloro-3-(4-chlorophenyl)-2H-1,4-benzoxazine CAS 112030-47-4

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

6-Chloro-3-(4-chlorophenyl)-2H-1,4-benzoxazine (CAS 112030-47-4), molecular formula C14H9Cl2NO and molecular weight 278.13 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, 6-Chloro-3-(4-chlorophenyl)-2H-1,4-benzoxazine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 278.13 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.

As a certified reference material (CRM), 6-Chloro-3-(4-chlorophenyl)-2H-1,4-benzoxazine 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.
