Longifolene

Longifolene is the common (or trivial) chemical name of a naturally occurring, oily liquid hydrocarbon found primarily in the high-boiling fraction of certain pine resins. Longifolene is used in organic synthesis for the preparation of dilongifolylborane, a chiral hydroborating agent. Longifolene is also one of two most abundant aroma constituents of lapsang souchong tea, because the tea is smoked over pine fires.

Maleic Acid

Maleic acid is an organic compound that is a dicarboxylic acid, a molecule with two carboxyl groups. It is the cis isomer of butenedioic acid. It is used in the preparation of fumaric acid by catalytic isomerization. It is also used as an oil and fat preservative and food acidulant.

Properties Suppliers
Methylamine

Methylamine is the organic compound. This colourless gas is a derivative of ammonia, where in one H atom is replaced by a methyl group. It is the simplest primary amine. It has a strong odor similar to fish. Methylamine is used as a building block for the synthesis of many other commercially available compounds. Representative commercially significant chemicals produced from methylamine include the pharmaceuticals ephedrine and theophylline, the pesticides carbofuran, carbaryl, and metham sodium, and the solvents N-methylformamide and N-methylpyrrolidone. The preparation of some surfactants and photographic developers require methylamine as a building block. Liquid methylamine can be used as a solvent analogous to liquid ammonia. It can also be used for scavenging H2S from hydrocarbon in refining applications.

Musk ketone

Musk Ketone is exclusively used for fragrance in cosmetic and perfumery applications. Musk Ketone is said to be an excellent fixative having properties of not only being a penetrating fragrance, but of being a persistent scent. Musk ketone closely resembles the odour of natural musk but is slightly sweeter than it.

Neocuproine

Neocuproine is a heterocyclic organic compound and chelating agent. Phenanthroline ligands were first published in the late 19th century, and the derivatives substituted at the 2 and 9 positions are among the most studied of the modified phenanthrolines. Neocuproine has also been discovered to have properties that cause fragmentation and disappearance of the melanin in adult zebrafish melanocytes. Those expressing eGFP also have been observed to lose eGFP fluorescence in the presence of neocuproine.

Properties Suppliers
Octabenzone

Octabenzone is a UV absorber or screener. It is used to protect polymers against damage by UV light.

Properties Suppliers
Oxalic Acid

Oxalic acid is a dicarboxylic acid. It's main applications include cleaning or bleaching, especially for the removal of rust. About 25% of produced oxalic acid is used as a mordant in dyeing processes. It is used in bleaches, especially for pulpwood.

Phosphorite

Phosphorite is a non-detrital sedimentary rock which contains high amounts of phosphate bearing minerals. The phosphate content of phosphorite is at least 15 to 20%, which is a large enrichment over the typical sedimentary rock content of less than 0.2%. The phosphate is present as fluorapatite Ca5(PO4)3F (CFA) typically in cryptocrystalline masses (grain sizes < 1 μm) referred to as collophane. It is also present hydroxyapatite Ca5(PO4)3OH, which is often dissolved from vertebrate bones and teeth, whereas fluorapatite can originate from hydrothermal veins. Other sources also include chemically dissolved phosphate minerals from igneous and metamorphic rocks. Phosphorite deposits often occur in extensive layers, which cumulatively cover tens of thousands of square kilometres of the Earth's crust. Phosphate rock is mined, beneficiated, and either solubilized to produce wet-process phosphoric acid, or smelted to produce elemental phosphorus. Phosphoric acid is reacted with phosphate rock to produce the fertilizer triple superphosphate or with anhydrous ammonia to produce the ammonium phosphate fertilizers. Elemental phosphorus is the base for furnace-grade phosphoric acid, phosphorus pentasulfide, phosphorus pentoxide, and phosphorus trichloride. Approximately 90% of phosphate rock production is used for fertilizer and animal feed supplements and the balance for industrial chemicals.
