Medchemexpress LLC Citric acid-13C2 | 224054-26-6 | 194.11 | 1 MG
Citric acid-13C2 is the 13C-labeled Citric acid. Citric acid is a natural preservative and food tartness enhancer. It induces apoptosis and cell cycle arrest at G2/M phase and S phase in HaCaT cells. Citric acid causes oxidative damage of the liver by means of the decrease of antioxidative enzyme activities. It is also an acidulant, emulsifier, sequestrant and buffering agent widely used across many industries.
- This compound can be used as a tracer.
- This compound can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
