Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 178.21 g/mol gives 1-ethyl-2-fluoro-5-methyl-1H-1,3-benzodiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-ethyl-2-fluoro-5-methyl-1H-1,3-benzodiazole (CAS 2296362-20-2) is a high-purity analytical reference standard with the molecular formula C10H11FN2 and a molecular weight of 178.21 g/mol.
The molecular framework of 1-ethyl-2-fluoro-5-methyl-1H-1,3-benzodiazole (C10H11FN2) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-ethyl-2-fluoro-5-methyl-1H-1,3-benzodiazole 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.
