2-Bromoazulene CAS 58312-57-5 chemical structure

Description

As a certified reference material (CRM), 2-Bromoazulene 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.

2-Bromoazulene (CAS 58312-57-5) is a high-purity analytical reference standard with the molecular formula C10H7Br and a molecular weight of 207.07 g/mol.

2-Bromoazulene (C10H7Br) contains bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
