What is Dimethyl Sulfone CAS 67-71-0?

Dimethyl Sulfone CAS 67-71-0 is an organic sulfur compound with the molecular formula C2H6O2S and molecular weight 94.13 g/mol. It is also known as methylsulfonylmethane or MSM and is used in supplements, foods and personal care products.

How is Dimethyl Sulfone related to DMSO?

Dimethyl sulfone is the oxidized form of dimethyl sulfoxide, commonly written DMSO2. It is a stable, odorless, water-soluble white crystalline material with different physical and application properties from DMSO.

What are the typical physical specifications for MSM?

High-purity MSM is generally a white crystalline powder or flakes with a melting point around 107-110 C. It is freely soluble in water and ethanol but only slightly soluble in ether, and food or pharma grades are controlled for purity, water content, ash and heavy metals.

What applications use Dimethyl Sulfone?

It is used in dietary supplements, functional foods, cosmetic formulations, and some topical personal care products. In supplements it may be combined with other joint-care ingredients, while in cosmetics it can function as a conditioning or formulation ingredient.

What quality points should a buyer check for MSM CAS 67-71-0?

Buyers commonly check assay, melting point, loss on drying, residue on ignition, heavy metals, bulk density and dimethyl sulfoxide impurity. The appropriate grade depends on whether the final use is food, dietary supplement, cosmetic or pharmaceutical.

Dimethyl Sulfone CAS 67-71-0

Dimethyl Sulfone (CAS 67-71-0) is an organic sulfur compound utilizing its high biological bioavailability as a key ingredient in dietary supplements for joint health and inflammation support. Chemically identified as Methylsulfonylmethane or MSM, this white crystalline powder acts as a natural sulfur donor essential for the synthesis of collagen and glucosamine. As a stable Sulfone derivative occurring naturally in trace amounts, it is extensively integrated into nutraceutical formulations, cosmetic anti-aging creams, and high-temperature industrial solvents. We ensure bulk supply capabilities for this material, providing access to competitive factory pricing and customized specifications to meet specific mesh sizes (e.g., 20-40 mesh, 60-80 mesh) and purity standards. Full technical documentation, including MSDS, TDS, COA, is available to support compliance and safety protocols.

Applications

Dimethyl Sulfone (MSM) is a versatile ingredient used globally in the health and wellness sectors:

Dietary Supplements (Joint Health):
- Used in capsules, tablets, and powders for joint care.
- Helps relieve osteoarthritis pain, reduce inflammation, and support cartilage recovery.
- Often combined with Glucosamine and Chondroitin.
Personal Care & Cosmetics:
- Skin Care: Promotes collagen production, helping to improve skin elasticity and reduce wrinkles.
- Hair & Nail: Strengthens hair and nails due to its sulfur content (keratin building block).
- Topical Creams: Used in pain relief gels and anti-acne formulations.
Animal Health:
- Widely used in supplements for racehorses and pets (dogs/cats) to maintain joint mobility and coat health.
Industrial Use:
- Used as a high-temperature solvent for organic synthesis.

Storage Conditions

Environment: Store in a cool, dry place. Avoid high humidity.
Temperature: Store at room temperature (below 30°C).
Packaging: Keep container tightly closed. The powder can be hygroscopic; ensure the liner is sealed after use to prevent clumping.
Stability: Stable under normal conditions. Avoid strong oxidizing agents.

Safety Precautions

Toxicity: Dimethyl Sulfone is generally considered non-toxic and is GRAS (Generally Recognized As Safe) for consumption.
Handling: Wear standard protective gear (dust mask, gloves, safety glasses) during handling to avoid dust inhalation or eye contact.
Eye Contact: If powder enters the eyes, rinse thoroughly with fresh water.
Skin Contact: Safe for skin, but wash with soap and water after handling bulk quantities for hygiene.
Fire Safety: Combustible at high temperatures. In case of fire, use water spray, dry chemical, or CO2.
