Chemical Structure

(E)-1,2-Di-p-tolylethene CAS 18869-29-9 chemical structure

Description

(E)-1,2-Di-p-tolylethene (CAS 18869-29-9) is a high-purity analytical reference standard with the molecular formula C16H16 and a molecular weight of 208.30 g/mol.

Based on its molecular formula C16H16, (E)-1,2-Di-p-tolylethene contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 208.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 (E)-1,2-Di-p-tolylethene 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.
