CAS 10101-41-4 corresponds to calcium sulfate dihydrate (commonly known as gypsum), with the chemical formula CaSO ₄ · 2H ₂ O. It is the most common natural hydrated form of calcium sulfate, a white crystalline solid, and slightly soluble in water.

Core Information
-Chinese name: Calcium sulfate dihydrate (gypsum)
-English name: Calcium sulfate dihydrate
-Molecular formula: CaSO ₄· 2H ₂ O (written as CaH ₄ O ₆ S)
-Molecular weight: 172.17
-Appearance: White crystalline powder or monoclinic crystal, odorless, slightly astringent
-Density: 2.32 g/cm ³
-Solubility: Slightly soluble in water (about 2 g/L, 20 ℃), soluble in acids, ammonium salts, glycerol, insoluble in ethanol
-Thermal behavior: At around 128 ℃, 1.5 molecules of water are lost to form hemihydrate calcium sulfate (gypsum), and above 163 ℃, it is completely dehydrated to anhydrous calcium sulfate; The melting point of anhydrous substance is about 1450 ℃
-Safety: Generally low toxicity, ADI does not require special regulations (FAO/WHO), and attention should be paid to the irritation of dust to the eyes/respiratory tract

main purpose
1. Building materials: cement retarder, gypsum board, model casting, chalk
2. Food industry: coagulants (soy products), dough conditioners, calcium fortifiers, canned tissue fortifiers (edible grade)
3. Agriculture: Soil amendments (reducing alkalinity and improving structure)
4. Chemical/Other: paint and paper fillers, pigments (Pigment White 25), pharmaceutical excipients, raw materials for sulfuric acid production

This substance is widely naturally present (gypsum ore) and is also an industrial byproduct such as phosphoric acid; Storage should be moisture-proof, avoid high temperatures, and avoid violent reactions with strong acids.
