1-Bromo-2-naphthalenecarboxaldehyde 1-bromo-2-naphthaldehyde 3378-82-3 (CAS 3378-82-3), molecular formula C11H17BrO and molecular weight 245.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Bromo-2-naphthalenecarboxaldehyde 1-bromo-2-naphthaldehyde 3378-82-3 (C11H17BrO) is characterized by a hydroxyl group, an ether linkage, bromine substitution. 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.
As a certified reference material (CRM), 1-Bromo-2-naphthalenecarboxaldehyde 1-bromo-2-naphthaldehyde 3378-82-3 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.
