Trimethylamine N-oxide-d9 is the deuterium-labeled internal standard of trimethylamine N-oxide (TMAO) used for quantitative analytical assays such as LC-MS and GC-MS. Supplied as a solid high-purity reference standard, it is intended for calibration, method validation, and trace-level quantification in biological and environmental samples.
- Deuterium-labeled internal standard for accurate quantification by LC-MS and GC-MS.
- High purity (99.76%) for reliable calibration and trace-level detection.
- Available in small pack sizes suitable for analytical workflows (1 mg-100 mg).
- Solid powder with recommended storage at -20°C for long-term stability; in solvent store at -80°C for best stability.
- Molecular weight 84.17 and molecular formula C3D9NO for unambiguous identification.
