6-bromo-5-chloro-3,4-dihydro-2H-1,4-benzoxazine CAS 1154740-67-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6-bromo-5-chloro-3,4-dihydro-2H-1,4-benzoxazine.

CATO supplies 6-bromo-5-chloro-3,4-dihydro-2H-1,4-benzoxazine (CAS 1154740-67-6), a certified reference material (molecular formula C8H13BrClNO, MW 254.55 g/mol) for analytical method development and quality control.

6-bromo-5-chloro-3,4-dihydro-2H-1,4-benzoxazine (C8H13BrClNO) contains an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), 6-bromo-5-chloro-3,4-dihydro-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.
