Description
CATO manufactures 1-Bromo-7-iodonaphthalene 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-7-iodonaphthalene (CAS 304458-73-9), molecular formula C10H6BrI and molecular weight 332.96 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-7-iodonaphthalene (C10H6BrI) contains bromine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 332.96 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
