79082-81-8 Usage
Chiral compound
2,2'-diamino-1-1'-binaphthyl (BINAM) is a chiral compound, meaning it has a structure that is not identical to its mirror image.
Two naphthyl rings
BINAM consists of two naphthyl rings, which are aromatic hydrocarbon rings with two pairs of double bonds.
Connected by a single bond
The two naphthyl rings in BINAM are connected by a single bond, which allows for some flexibility in the molecule.
Two amino groups
BINAM has two amino groups (-NH2) attached to the central carbon atom, which can form hydrogen bonds and coordinate with metal ions.
Widely used as a chiral ligand
BINAM is commonly used as a chiral ligand in asymmetric catalysis, particularly in metal-catalyzed reactions.
Effectively differentiates between enantiomers
The unique structure of BINAM allows it to effectively differentiate between enantiomers, making it a valuable tool in the synthesis of chiral compounds.
Check Digit Verification of cas no
The CAS Registry Mumber 79082-81-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,0,8 and 2 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 79082-81:
(7*7)+(6*9)+(5*0)+(4*8)+(3*2)+(2*8)+(1*1)=158
158 % 10 = 8
So 79082-81-8 is a valid CAS Registry Number.

Sannicolo, Franco
, p. 119 - 120 (1985)
2,2'-Hydrazonaphthalene rearranges in the presence of (+)-camphor-10-sulfonic acid to give 2,2'-diamino-1,1'-binaphthyl with optical yields up to 15percent in the (-)-enantiomer.Enantioselectivity is dependent on temperature and solvent.
