Synonyms: Methylsulfonylmethane; MSM; Methyl sulfone; DMSO2; Sulfonylbismethane.

CAS: 67-71-0.

It has a molecular weight of 94.13 g/mol and appears as a white crystalline powder or flakes.

It has a melting point of about 107–110 °C and is freely soluble in water and ethanol but only slightly soluble in ether.

High-purity food, supplement, cosmetic and pharmaceutical grades have an assay of not less than 99.90%.

It is odorless and has a slightly bitter taste.

It is the oxidized form of dimethyl sulfoxide (DMSO), often written as DMSO2, and is more stable for oral use.

It is used in joint-care dietary supplements, capsules, tablets and powders.

It is often combined with glucosamine and chondroitin in joint-support formulations.

It is used in skin, hair and nail care products as a sulfur source and conditioning ingredient.

It is used in topical creams, pain-relief gels and anti-acne formulations.

It is used in animal nutrition supplements for joint mobility and coat condition.

It is used as a high-temperature solvent in organic synthesis.

Confirm appearance, assay, melting point, loss on drying, residue on ignition, heavy metals, bulk density, DMSO impurity, solubility, odor and taste.

Store in a cool, dry place at room temperature below 30 °C and keep containers tightly closed, as the powder is hygroscopic.

Confirm packaging with the requested quantity and destination requirements.
