Compared with other compounds in its class, the molecular weight of 294.39 g/mol gives 1,1'-((2,3,5,6-Tetramethyl-1,4-phenylene)bis(methylene))bis(1H-imidazole) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,1'-((2,3,5,6-Tetramethyl-1,4-phenylene)bis(methylene))bis(1H-imidazole) (CAS 1012075-54-5), molecular formula C18H22N4 and molecular weight 294.39 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,1'-((2,3,5,6-Tetramethyl-1,4-phenylene)bis(methylene))bis(1H-imidazole) (C18H22N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 1,1'-((2,3,5,6-Tetramethyl-1,4-phenylene)bis(methylene))bis(1H-imidazole) 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.
