Medchemexpress LLC Ethylmalonic acid-d3 | 70907-93-6 | 98.0% | 135.13 | 1 MG
Ethylmalonic acid-d3 is the deuterium labeled Ethylmalonic acid. It is a short-chain organic dicarboxylic acid that synergistically induces mitochondrial permeability transition (MP) with Ca2+, inhibits Mi-CK, and disrupts mitochondrial energy metabolism. It can be used in the research of SCADD, EE, and other genetic metabolic diseases characterized by EMA accumulation.
- Can be used as a tracer.
- Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.
- Deuteration has potential to affect pharmacokinetic and metabolic profiles of drugs.
