Chemical Structure
Description
The occurrence of 1-Bromo-2-(difluoromethyl)naphthalene is closely related to fluorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Bromo-2-(difluoromethyl)naphthalene (CAS 925441-52-7), molecular formula C11H7BrF2 and molecular weight 257.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-2-(difluoromethyl)naphthalene (C11H7BrF2) is characterized by fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Bromo-2-(difluoromethyl)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.
