Chemical Structure
Description
1,4-Bis(3-fluorobenzyl)-1,4-diazepane (CAS 1261235-23-7), molecular formula C19H22F2N2 and molecular weight 316.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,4-Bis(3-fluorobenzyl)-1,4-diazepane (C19H22F2N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine 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.
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 1,4-Bis(3-fluorobenzyl)-1,4-diazepane 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.
