Medchemexpress LLC Ivacaftor-d9 | 1413431-07-8 | 99.8% | C24H19D9N2O3 | 10MG
Ivacaftor-d9 is a deuterium-labeled isotopologue of ivacaftor used as an analytical reference and internal standard for LC-MS/MS, pharmacokinetic, and ADME studies. The nine deuterium atoms enable unambiguous mass separation from non-labeled ivacaftor, improving assay specificity and quantitation.
- Deuterated internal standard for LC-MS/MS assays.
- Enables accurate quantification and reduced matrix effects.
- Suitable for pharmacokinetic and ADME studies.
- High chemical purity (99.8%).
- Stable under typical laboratory storage conditions.
Cayman Chemical DeoxycholIc AcId 10g
A secondary bile acid; inhibits TCA-induced spore germination in seven C. difficile strains at 0.2% v/v; inhibits growth and decreases the cytotoxicity of C. difficile culture supernatants to Vero cells at 0.02% v/v; inhibits ionizing radiation-induced p53-dependent transcription in a reporter assay using HCT116 cells at 200 µM; fecal and intestinal tissue levels are increased in a rat model of high-fat diet-induced obesity compared with rats fed a normal diet; increased serum levels have been found in patients with colorectal cancer
