Chemical Structure
Description
Based on its molecular formula C7HD5O3, 3-Hydroxybenzoic acid-d5 contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 143.15 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).
3-Hydroxybenzoic acid-d5 (CAS 2098655-86-6), molecular formula C7HD5O3 and molecular weight 143.15 g/mol, is a CATO reference standard with documented purity and traceability.
