Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 235.12 g/mol gives 2-(2-Bromoethyl)naphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(2-Bromoethyl)naphthalene (CAS 2086-62-6) is a high-purity analytical reference standard with the molecular formula C12H11Br and a molecular weight of 235.12 g/mol.
Structurally, 2-(2-Bromoethyl)naphthalene (C12H11Br) contains bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 235.12 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 2-(2-Bromoethyl)naphthalene 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.
