Glyoxal 40%
Colorless or pale yellow prismatic crystal or liquid, crystal easy to deliquescence. The vapor is green and burns with a purple flame. Soluble in water, easily soluble in common organic solvents. It is used as a solubilizer and cross-linking agent in polymer chemistry; it is used in organic synthesis, especially when building heterocycles such as imidazoles.
Hydrazine Sulfate
Hydrazine sulfate is the salt of hydrazine and sulfuric acid. Known by the trade name Sehydrin, it is a chemical compound that has been used as analternative medical treatment for the loss of appetite (anorexia) and weight loss (cachexia) which is often associated with cancer. Hydrazine sulfate has never been approved in theUSas safe and effective in treating any medical condition, although it is marketed as a dietary supplement. It is also sold over the Internet by websites that promote its use as a cancer therapy. The active ingredient is hydrazine, and the sulfate component is present to aid in formulation.
Imidazole
Imidazole can be used in imidzaole antifungal drug: miconazole, econazole, clotrimazole and ketoconazole. It is also the intermediate of ardiovascular drug, ingredient of perservative and curing agent of epoxy resin.
Iminodisuccinic Acid Sodium(IDS)
As a complexing agent, it is used in alkaline earth metal and heavy metal ion cleaning agents, widely used in industrial cleaning agents, detergents, textile printing and dyeing auxiliaries, pulp and paper industry, hydrogen peroxide stabilizer, electronic chemicals, copper complexing agent, ceramic industry , electroplating industry, cleaning agent for photography industry, extraction of soil heavy metal pollutants, soil trace element fertilizer chelating agent, etc.
Isopropanol
Isopropanol is also called fire wine, dimethyl methanol, 2-propanol, the simplest secondary alcohol, and one of the isomers of n-propanol. A colorless, flammable liquid with a strong odor. It smells like a mixture of ethanol and acetone, and its odor is not great. It is soluble in most organic solvents such as water, alcohol, ether, benzene, chloroform, and can be miscible with water, alcohol and ether, and can form an azeotrope with water. Density (specific gravity): 0.7863g/cm3, melting point: -88.5°C, boiling point: 82.5°C, flash point: 11.7°C, spontaneous ignition point: 460°C, refractive index: 1.3772. Its steam can cause slight irritation to the eyes, nose and throat; it can be absorbed by the body through the skin. Its vapor and air can form an explosive mixture. The explosion limit is 2.0%~12% (volume). Belongs to a medium explosive dangerous goods. It is a flammable and low-toxic substance. The toxicity of vapor is twice that of ethanol, but the toxicity is opposite when taken orally.
Lead Oxide
Lead tetraoxide is most often used as a pigment for primer paints for iron objects.Currently it is mostly used for manufacture of glass, especially lead glass (crystal glass). Red lead is used as a curing agent in some polychloroprene rubber compounds. It is used in place of magnesium oxide to provide better water resistance properties.
Lead Oxide
Lead(II) oxide, also called lead monoxide, is the inorganic compound with the molecular formula PbO. PbO occurs in two polymorphs, one litharge having a tetragonal crystal structure and the other massicot having an orthorhombic crystal structure. Modern applications for PbO are mostly in lead-based industrial glass and industrial ceramics, including computer components.
Lithium Hexafluorophosphate
White crystal or powder, relative density 1.50, strong deliquescent; easily soluble in water, but also soluble in low-concentration methanol, ethanol, propanol, carbonate and other organic solvents. Decomposes when exposed to air or heated. It is mainly used for lithium-ion power batteries, lithium-ion energy storage batteries and other daily-use batteries. It is also an irreplaceable electrolyte for lithium-ion batteries in the near and mid-term.
Lithium Hydroxide
Lithium hydroxide is mainly consumed for the production of lithium greases. A popular lithium grease is lithium stearate, which is a general-purpose lubricating grease due to its high resistance to water and usefulness at both high and low temperatures. It is also used as a heat transfer medium and as a storage-battery electrolyte.
Luminol
Yellow crystalline powder. Easily soluble in lye, soluble in dilute acid, almost insoluble in water, and insoluble in alcohol. Neutral or slightly acidic solutions exhibit strong bright blue fluorescence when exposed to ultraviolet light. For chemiluminescence analysis, such as: metal cations, blood and glucocorticoids. By 3-nitrophthalic acid by cyclization, derived from reduction. 3-Nitrophthalic acid was added to 8% aqueous hydrazine solution, and the solid was dissolved by heating. Add ethylene glycol, evaporate the excess water in the solution in an evaporator, heat at 215-220°C for 2min, Chemicalbook closes the heterocyclic ring, and cools to obtain a yellow nitro compound. Cool, add 10% sodium hydroxide solution, stir, add sodium dithionate, heat to boiling, keep the temperature for 5 min, add acetic acid again, and cool to obtain a bright yellow product. After standing overnight, the product was obtained by filtration.
M-Toluic Acid
M-Toluic Acid, (IUPAC: 3-methylbenzoic acid), is an aromatic carboxylic acid, with formula (CH3)C6H4(COOH). It is an isomer of p-toluic acid and o-toluic acid. It serves, among other purposes, as a precursor to DEET (N,N-diethyl-m-toluamide), the well-known insect repellent.
Magenta
Yellow-green flashing crystalline lump or sand. Soluble in cold and hot water, it is reddish purple, and easily soluble in alcohol, it is red. In case of concentrated sulfuric acid, it is yellow-brown, almost colorless after dilution. Its aqueous solution and sodium hydroxide solution are almost colorless liquid with red precipitate. For the preparation of Schiff’s reagent to detect aldehydes, for the determination of some acid ions and metal ions by extraction photometry. Also used for photometric detection of bromine, nitrite and sulfur dioxide. Used as a maximal inhibitor in polarographic analysis. It is also used as a nuclear dye for biochemical analysis. It is the strongest nuclear dye. It can stain mucin, elastic tissue and fuchsin granules, and nuclear staining of the central nervous system. It is used to identify Mycobacterium tuberculosis in bacteriology, and it is formulated in analytical chemistry. Schiff’s reagent tests for aldehydes. Redox indicator for titration with bromate.
