Medchemexpress LLC Apalutamide-13C,d3 | 956104-40-8 | 99.9% | 481.45 | 1 MG
SDP

Apalutamide-13C,d3 is a 13C- and deuterium labeled form of Apalutamide (ARN-509), a potent and competitive androgen receptor (AR) antagonist. This compound incorporates stable heavy isotopes of hydrogen, carbon, and other elements, making it suitable for quantitative analysis during drug development processes. Deuteration has also garnered attention for its potential to affect the pharmacokinetic and metabolic profiles of drugs.

  • Potent and competitive androgen receptor (AR) antagonist.
  • Binds AR with an IC50 of 16 nM.
  • Can be used as a tracer.
  • Can be used as an internal standard for quantitative analysis by NMR, GC-MS, or LC-MS.

Medchemexpress LLC Phytanic acid-d3 | 1383920-40-8 | 99.1% | 315.55 | C20H37D3O2 | 5 MG
SDP

Phytanic acid-d3 is a deuterium-labeled analogue of phytanic acid used as an internal standard for accurate quantitation by GC- or LC-MS in biochemical and clinical research. It has molecular formula C20H37D3O2, molecular weight 315.55, and CAS 1383920-40-8, and is supplied in research-scale quantities for analytical use.

  • Intended for use as an internal standard in GC- or LC-MS assays.
  • Deuterium labeling provides a distinct mass shift for reliable differentiation from the native analyte.
  • Coelutes with native phytanic acid to support accurate quantitation.
  • Offered in small research-scale quantities suitable for method development and standard curves.
  • High isotopic and chemical purity supports precise measurement.
