Medchemexpress LLC Fumaric acid-d4 | 194160-45-7 | MFCD00190450 | 98.0% | 120.10 | C4D4O4 | 10 MG
Fumaric acid-d4 is the deuterium-labeled form of fumaric acid used as a stable isotope tracer and internal standard for quantitative and metabolic studies. It is intended for research use and is commonly applied in analytical workflows where isotopic labeling improves detection, tracking, and quantitation of fumaric acid-related metabolites.
- Deuterium labeled for tracer and internal standard applications.
- Suitable for NMR, GC-MS, and LC-MS quantitation.
- High purity (98%) for analytical workflows.
- Solid powder with recommended low-temperature storage.
- Available in small, research-scale sizes for analytical use.
Medchemexpress LLC Corticosterone-d8 | 1271728-07-4 | 99.9% | 1 MG
Corticosterone-d8 is the deuterium labeled Corticosterone. Corticosterone is an adrenocortical steroid that has modest but significant activities as a mineralocorticoid and a glucocorticoid.
- Can be used as a tracer.
