Description
CATO manufactures 1-Bromo-4-(chloromethyl)naphthalene 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.
1-Bromo-4-(chloromethyl)naphthalene (CAS 101828-11-9), molecular formula C11H8BrCl and molecular weight 255.54 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H8BrCl, 1-Bromo-4-(chloromethyl)naphthalene contains chlorine/bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 255.54 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
