(RS)-S-Adenosyl-L-methionine-d3 (S-methyl-d3) Tetra(p-toluenesulfonate) Salt is a stable, deuterium-labeled internal standard for SAM. It features isotopic substitution at the S-methyl group to ensure accurate quantification in mass spectrometry assays without metabolic interference.
Store under inert atmosphere at -20°C to prevent hydrolysis. Use appropriate PPE during handling as the salt form may be hygroscopic and irritating. Not intended for direct clinical administration; strictly for research use only.
