In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called The polymorphism of organic compounds, published in 1961, which mentions a compound: 560-09-8, mainly applied to , Product Details of 560-09-8.
Observations were made of the polymorphic transformations of organic compounds on the stage of a polarizing microscope. The crystals were cooled to -165° and heated to 200°. Under normal pressure polymorphism could not be proved for several compounds Enantiotropic pseudotransition was exhibited by phenol at -2°, caused by impurities. 1-Methylcyclopentanol, phenol, cyclopentyl cyanide, Me3COH, and CHI3 showed no true polymorphism. MeCN was not enantiotropic. Glutaric acid, lauryl alc., chloral hydrate, Me2C(Et)OH, and succinonitrile were enantiotropic. Hydroquinone, malonitrile, and Me oxalate were dimorphic monotropes. d-Camphoric acid was a true monotrope. 55 references.
I hope my short article helps more people learn about this compound((1S,3R)-1,2,2-Trimethylcyclopentane-1,3-dicarboxylic acid)Product Details of 560-09-8. Apart from the compound(560-09-8), you can read my other articles to know other related compounds.
