Industry:Chemistry
Any member of a group of synthetic, helical arrays of molecules formed by the chemical recognition and organization of metals and organic bases.
Industry:Chemistry
Aromatic polyester copolymers that have characteristically high-temperature resistance, yet can be melted and molded. Upon melting, the polymer chains undergo parallel ordering in the direction of the flow, resulting in superior mechanical properties in that direction.
Industry:Chemistry
C<sub>10</sub>H<sub>6</sub>(OH)<sub>2</sub> Crystals with a melting point of 124–125_C; soluble in ether, alcohol, and water; used as a reagent for sugars and oils, and to determine glucuronic acid in urine.
Industry:Chemistry
C<sub>16</sub>H<sub>23</sub>NO<sub>2</sub>_HCl A white, crystalline powder with a bitter taste and a melting point of 172–175_C; soluble in water, chloroform, and alcohol; used in medicine.
Industry:Chemistry
(C<sub>2</sub>H<sub>5</sub>)<sub>2</sub>NCS<sub>2</sub>Na A solid that is soluble in water and in alcohol; the trihydrate is used to determine small amounts of copper and to separate copper from other metals.
Industry:Chemistry
CH<sub>3</sub>COBr A colorless, fuming liquid with a boiling point of 81°C; soluble in ether, chloroform, and benzene; used in organic synthesis and dye manufacture.
Industry:Chemistry
A carbon atom with four different atoms or groups of atoms bonded to it. Also known as chiral carbon atom; stereogenic center.
