Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Benzenamine, 4,4'-methylenebis-, polymer with 2-(chloromethyl)oxirane (CAS 28390-91-2) is a high-purity analytical reference standard with the molecular formula C13H14N2C3H5ClO and a molecular weight of 290.79 g/mol.
Based on its molecular formula C13H14N2C3H5ClO, Benzenamine, 4,4'-methylenebis-, polymer with 2-(chloromethyl)oxirane contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 290.79 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures Benzenamine, 4,4'-methylenebis-, polymer with 2-(chloromethyl)oxirane 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.
