The compound you're asking about appears to be a slight misnomer. The correct and incredibly important molecule you are referring to is:

BINAP, or more precisely, 2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl.

This is one of the most famous and successful chiral ligands in the history of chemistry. Its structure consists of two naphthalene rings linked at the 1 and 1' positions (the "binaphthyl" core), with a diphenylphosphine (–PPh₂) group attached to the 2 and 2' position of each naphthyl ring.

It exists in two mirror-image forms: (R)-BINAP and (S)-BINAP. This three-dimensional "chiral" shape is the source of its immense utility.

Primary Use: Asymmetric Catalysis

BINAP's sole and revolutionary use is as a ligand in transition metal catalysts to perform asymmetric synthesis—creating molecules with a specific "handedness" (chirality). This is crucial in pharmaceuticals, where typically only one enantiomer of a drug is therapeutically active.

When bound to a metal center (like Ruthenium, Rhodium, or Palladium), the rigid, chiral pocket of BINAP steers a chemical reaction to produce one chiral product overwhelmingly over its mirror image.

Key Reactions and Impact:

Asymmetric Hydrogenation (Nobel Prize-Winning Chemistry):

This is BINAP's most celebrated application. (R)-BINAP-Ruthenium complexes, developed by Ryoji Noyori, can hydrogenate a wide range of functional groups (like ketones and olefins) with extremely high enantioselectivity.
Industrial Example: The synthesis of (-)-menthol by Takasago International, which produces thousands of tons annually using a BINAP-Rhodium catalyst.

Asymmetric Isomerization:

A BINAP-Rhodium catalyst efficiently converts allylic amines to chiral enamines, a key step in the commercial synthesis of the antibiotic (-)-chloramphenicol.

Other Carbon-Carbon Bond Forming Reactions:

BINAP-Palladium complexes are used in asymmetric versions of reactions like the Heck reaction (C–C coupling) and hydrosilylation.

Why It's So Significant:

High Efficiency & Selectivity: It provides exceptional enantioselectivity (often >99%) for many reactions.
Broad Substrate Scope: It works on a wide variety of starting materials, making it a versatile tool.
Industrial Viability: Its robustness and effectiveness have made it a mainstay for large-scale manufacturing of single-enantiomer chemicals, especially pharmaceuticals (e.g., antibiotics, antihypertensive agents, and anti-inflammatory drugs).

In summary, 1,1'-Binaphthyl-2,2'-diphosphine (BINAP) is not a drug or material itself. It is a foundational tool of modern synthetic chemistry—a chiral ligand that enables the industrial-scale production of pure, single-handed enantiomers of complex molecules, which is a cornerstone of contemporary drug development and fine chemical synthesis. Its development was a milestone that earned Ryoji Noyori the 2001 Nobel Prize in Chemistry.
