Chemical Structure

Thioctic acid Impurity 91 CAS CATO-C4X-152691 chemical structure

Description

Based on its molecular formula C8H13ClO2, Thioctic acid Impurity 91 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 176.64 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.

Thioctic acid Impurity 91 (CAS CATO-C4X-152691) is a certified pharmaceutical impurity reference standard with the molecular formula C8H13ClO2 and a molecular weight of 176.64 g/mol.
