Frequently Asked Questions
What is methylsulfonylmethane (MSM)?
MSM (CAS 67-71-0), or dimethyl sulfone ((CH3)2SO2), is a high-purity organosulfur compound. RawSource supplies it as a 40-mesh granular grade used as a polar solvent and as an ingredient in dietary-supplement blends.
What does the 40-mesh designation mean?
40 mesh specifies the particle size of the granular grade, controlling flow and blending consistency in dry formulations. The 40-mesh grade is supplied for uniform mixing in supplement and process blends.
Is MSM the same as DMSO?
No. MSM is dimethyl sulfone ((CH3)2SO2, CAS 67-71-0), a solid; DMSO is dimethyl sulfoxide, a liquid. MSM is the more fully oxidized (sulfone) compound, while DMSO is the sulfoxide.
What is methylsulfonylmethane used for industrially?
As dimethyl sulfone, it serves as a high-boiling polar solvent for organic and inorganic solutes and as an organosulfur ingredient in supplement blends. The CAS number is 67-71-0 and the HS code is 2930.90 (organo-sulfur compounds, other).
What bulk packaging and documentation are available?
RawSource supplies the 40-mesh granular grade in bulk with a Certificate of Analysis and Safety Data Sheet per shipment. Request a bulk quote with your target volume and grade for current pricing and lead time.
