Chemical Structure
Description
As a certified reference material (CRM), 5-Bromo-2-chloroanisole 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.
5-Bromo-2-chloroanisole (CAS 16817-43-9) is a high-purity analytical reference standard with the molecular formula C7H12BrClO and a molecular weight of 227.53 g/mol.
Structurally, 5-Bromo-2-chloroanisole (C7H12BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 227.53 g/mol, it falls into the medium-molecular-weight range. 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.
