Description
CATO manufactures 1,4-Dimethyl-5-propylnaphthalene 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.
1,4-Dimethyl-5-propylnaphthalene (CAS 204256-08-6), molecular formula C15H18 and molecular weight 198.30 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H18, 1,4-Dimethyl-5-propylnaphthalene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.30 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
