Medchemexpress LLC Stearic acid-d5 | 211443-83-3 | ≥99% | 100 MG
Stearic acid-d5 is a deuterium labeled stearic acid, a long-chain dietary saturated fatty acid found in various animal and vegetable fats and oils. It is commonly used as an internal standard for the quantification of stearic acid by GC- or LC-MS. Deuterium labeling incorporates stable heavy isotopes into molecules, which can serve as tracers for quantitation during drug development and may impact pharmacokinetic and metabolic profiles of drugs.
- Used as an internal standard for quantification.
- Deuterium labeled.
- Functions as a tracer for quantitation during drug development.
- May affect pharmacokinetic and metabolic profiles.
- Long-chain saturated fatty acid.

Medchemexpress LLC Sitagliptin-d4 hydrochloride | 486460-32-6 | 99.2% | 447.80 | 1 MG
Sitagliptin-d4 hydrochloride is the deuterium labeled Sitagliptin hydrochloride. This compound is an orally active and highly selective DPP4 inhibitor with an IC50 value of 19 nM. It blocks the degradation of glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic peptide (GIP) by competing inhibition (Kᵢ = 1 nM), thereby increasing active incretin levels. It can also directly stimulate GLP-1 secretion by intestinal L cells, independent of DPP-4, by activating cAMP/PKA and ERK1/2 pathways. Sitagliptin hydrochloride shows protective effects on pancreatic islet grafts in type 1 diabetes models and can be used for studying type 1 and type 2 diabetes.
- 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.
