Chemical Structure
Description
The occurrence of 1,5-Dibromo-2,6-dimethylnaphthalene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5-Dibromo-2,6-dimethylnaphthalene (CAS 20027-95-6), molecular formula C12H10Br2 and molecular weight 314.02 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,5-Dibromo-2,6-dimethylnaphthalene (C12H10Br2) is characterized by bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
CATO manufactures 1,5-Dibromo-2,6-dimethylnaphthalene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
