Oxindole (2-indolone) is an aromatic heterocyclic organic compound with the formula C 6 H 4 CH 2 C(O)NH. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing ring. Oxindole is a modified indoline with a substituted carbonyl at the second position of the 5-member indoline ring ...
Food-grade lubricants are specialized industrial lubricants designed for use in environments where there is potential for incidental contact with food or beverages.
The Gmelin rare earths handbook lists 1522 °C and 1550 °C as two melting points given in the literature, the most recent reference [Handbook on the chemistry and physics of rare earths, vol.12 (1989)] is given with 1529 °C.

Melting point: 125 to 126 °C (257 to 259 °F; 398 to 399 K) ... Horsfiline is an oxindole alkaloid found in the plant Horsfieldia superba, [1] which is used in ...
For example, the melting point of silicon at ambient pressure (0.1 MPa) is 1415 °C, but at pressures in excess of 10 GPa it decreases to 1000 °C. [13] Melting points are often used to characterize organic and inorganic compounds and to ascertain their purity. The melting point of a pure substance is always higher and has a smaller range than ...
Indole-3-acetic acid (IAA, 3-IAA) is the most common naturally occurring plant hormone of the auxin class. It is the best known of the auxins, and has been the subject of extensive studies by plant physiologists. [1]
Isatin, also known as tribulin, is an organic compound derived from indole with formula C 8 H 5 NO 2.The compound was first obtained by Otto Linné Erdman [1] and Auguste Laurent [2] in 1840 as a product from the oxidation of indigo dye by nitric acid and chromic acids.
