Methylsulfinylmethane (CAS 67-71-0), or MSM, is a high-purity organosulfur compound supplied as colorless crystals or white crystalline powder, a stable oxidative metabolite of DMSO that provides a bioavailable source of organic sulfur for joint-health supplements, cosmetic creams, hair treatments and livestock and horse feed premixes. Technically known as Dimethyl Sulfone , this compound is a stable oxidative metabolite of DMSO used to modulate inflammatory pathways. In industrial production, it is refined to 99.9% Purity to meet stringent safety standards for human and animal nutrition. The material is Thermally Stable and chemically inert, allowing for seamless integration into tablets, capsules, and topical gels. It serves as a Synergistic Agent in joint-health formulations, enhancing the structural integrity of biological matrices.
