Chemical Structure
Description
Based on its molecular formula C8H10Cl2O2, 1R-trans-Permethrinic Acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 209.07 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 1R-trans-Permethrinic Acid (CAS 55701-03-6), a certified reference material (molecular formula C8H10Cl2O2, MW 209.07 g/mol) for analytical method development and quality control.
