(1-~13~C)Octadecanoic acid(CAS: 85541-42-0)

(1-13C)Octadecanoic acid, also known as 13C-18:0, is a stable isomer of stearic acid labeled with 13C. It is used as an internal standard in analytical chemistry for the detection and quantification of unlabeled stearic acid.

(1-13C)Octadecanoic acid is primarily used as an internal standard in analytical chemistry, particularly in gas chromatography and mass spectrometry for the accurate quantification of stearic acid in various samples such as food, pharmaceuticals, and environmental samples.

(1-13C)Octadecanoic acid is considered safe for its intended use as an analytical standard. However, users should handle it with standard safety precautions, including wearing appropriate personal protective equipment (PPE) and ensuring proper ventilation during handling.

(1-13C)Octadecanoic acid should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a tightly sealed container to prevent contamination and degradation. Maintain a stable temperature and avoid exposure to moisture and strong acids or bases.
