Chemical Structure
Description
1-(Difluoromethyl)-3-iodonaphthalene (CAS 1261676-56-5), molecular formula C11H7F2I and molecular weight 304.07 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Difluoromethyl)-3-iodonaphthalene (C11H7F2I) is characterized by fluorine/iodine 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 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.
CATO manufactures 1-(Difluoromethyl)-3-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.
