R)-1-Aminoindane is a 1-aminoindane derivative. [1] It is specifically the (R)-enantiomer of 1-aminoindane, which is a racemic mixture of (R)- and (S)-enantiomers. [8] 1-Aminoindane is structurally related to 2-aminoindan. [1] A number of derivatives of 1- and 2-aminoindane are known. [1]
There are three common naming conventions for specifying one of the two enantiomers (the absolute configuration) of a given chiral molecule: the R/S system is based on the geometry of the molecule; the (+)- and (−)- system (also written using the obsolete equivalents d- and l-) is based on its optical rotation properties; and the D/L system is based on the molecule's relationship to ...
In chemistry, a racemic mixture or racemate (/ r eɪ ˈ s iː m eɪ t, r ə-, ˈ r æ s ɪ m eɪ t / [1]) is one that has equal amounts of left- and right-handed enantiomers of a chiral molecule or salt. Racemic mixtures are rare in nature, but many compounds are produced industrially as racemates.
Direct enantiomer separation involves the formation of a transient rather than covalent diastereomeric complexation between the chiral selector/discriminator and the analyte (drug enantiomer). In this approach, the subtle energy differences between the reversibly formed noncovalent diastereomeric complexes are exploited for chiral recognition.
An enantiopure drug is a pharmaceutical that is available in one specific enantiomeric form. Most biological molecules (proteins, sugars, etc.) are present in only one of many chiral forms, so different enantiomers of a chiral drug molecule bind differently (or not at all) to target receptors.

Esketamine, sold under the brand names Spravato (for depression) and Ketanest (for anesthesia) among others, [10] [12] is the S(+) enantiomer of ketamine. [5] [13] It is a dissociative hallucinogen drug used as a general anesthetic and as an antidepressant for treatment of depression.
