Chemical Structure
Description
2-Bromo-1-naphthaldehyde (CAS 269066-75-3), molecular formula C11H7BrO and molecular weight 235.08 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-Bromo-1-naphthaldehyde (C11H7BrO) is characterized by a hydroxyl group, an ether linkage, 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).
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), 2-Bromo-1-naphthaldehyde 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.
