It is pale yellow liquid that crystallizes in two forms, called α (−9.27 °C) and β (−3.17 °C). It is mainly a precursor to o-toluidine, which is an intermediate in the production of various dyes. [4]
It is one of the prototypical organic azides. It is a pale yellow oily liquid with a pungent odor. The structure consists of a linear azide substituent bound to a phenyl group. The C−N=N angle is approximately 120°. It was discovered in 1864 by Peter Griess by the reaction of ammonia and phenyldiazonium. [2] [3]
Jasmone is an organic compound, which is a volatile portion of the oil from jasmine flowers. It is a colorless to pale yellow liquid. Jasmone can exist in two isomeric forms with differing geometry around the pentenyl double bond, cis-jasmone and trans-jasmone.
It is described as a pale yellow liquid with a pungent odour by Leopold Gmelin. It is decomposed to iodoform by potash. [1] Iodal was discovered and named in 1837. [2] Iodal is synthesised from ethanol and iodine with concentrated nitric acid as the catalyst. [1] Its hydrate was described as water-soluble, white silky crystals. [3]
Castor oil is a vegetable oil pressed from castor beans, the seeds of the plant Ricinus communis. [1] The seeds are 40 to 60 percent oil. [2] It is a colourless or pale yellow liquid with a distinct taste and odor.
trans-2-Hexenal is an organic unsaturated aldehyde with a six-carbon chain. This clear, pale yellow liquid has a green, leafy, herbal fruit smell. It occurs naturally in a wide variety of plants, fruits, vegetables, and spices, and appears to be an important mediating and signalling chemical in plant-fungus and plant-insect interactions, such as the symbiosis between acacia ants and Acacias.
Thiazole itself is a pale yellow liquid with a pyridine-like odor and the molecular formula C 3 H 3 NS. [2] The thiazole ring is notable as a component of the vitamin thiamine (B 1 ). Molecular and electronic structure
