Palmitic Acid-13C16 (Cat No.:C000868) is a stable isotope-labeled form of palmitic acid, a common saturated fatty acid found in various natural sources, including plants and animals. The “-13C16” in the compound’s name indicates that all sixteen carbon atoms in palmitic acid have been replaced with the stable carbon-13 isotope. Deuterated and isotopically labeled compounds like this are widely used as internal standards in analytical chemistry, particularly in mass spectrometry and NMR spectroscopy. Palmitic Acid-13C16 serves as a reference standard for isotopic tracing and quantification studies, providing insights into fatty acid metabolism and lipid biochemistry.
