Chemical Structure
Description
The occurrence of ((E)-3-chloro-1-methyl-propenyl)-benzene is closely related to chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies ((E)-3-chloro-1-methyl-propenyl)-benzene (CAS 1794-51-0), a certified reference material (molecular formula C10H11Cl, MW 166.65 g/mol) for analytical method development and quality control.
((E)-3-chloro-1-methyl-propenyl)-benzene (C10H11Cl) contains chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures ((E)-3-chloro-1-methyl-propenyl)-benzene 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.
