Selenium disulfide is an inorganic compound composed of selenium and sulfur, with the chemical formula SeS₂. It typically appears as orange-yellow to reddish-brown crystals or powder with a distinctive odor. It is virtually insoluble in water and most organic solvents, chemically stable at room temperature, and renowned for its significant antifungal, anti-seborrhea, and keratolytic properties. It serves as a key raw material in personal care, pharmaceutical, and specialty materials industries.

Electronics & Semiconductors: As a semiconductor material, used in research or fabrication of optoelectronic devices and solar cells.
Q1: What distinguishes pharmaceutical-grade from industrial-grade products? How should one choose?
A2: Key differences lie in purity standards, impurity control, and intended applications. Pharmaceutical-grade products must meet pharmacopoeia standards (e.g., selenium content 52.0%-55.5%) for use in pharmaceuticals and high-end cosmetics. Industrial-grade products serve sectors like rubber and coatings. Selection depends on your end-product application and regulatory requirements.
Q2: How should products be stored correctly? What is the shelf life?
A2: Store in a cool, dry place, protected from light and sealed. Due to its chemical stability, shelf life is typically long under proper storage conditions. Refer to the product report for each batch for specific duration.
Q3: Can customized particle sizes and packaging be provided? What is the minimum order quantity?
A3: Customization is available. We tailor packaging to your production requirements, ranging from vacuum-sealed bags to bulk drums. Small-batch samples are available for testing. Contact sales for specific MOQ details.
Each batch is supplied with:
Certificate of Analysis (COA)
Technical Data Sheet (TDS)
