For any chemist or procurement specialist, a thorough understanding of a chemical intermediate's properties is fundamental to its successful application. (1S,2S)-1,2-Diphenylethane-1,2-diamine ((1S,2S)-DPEN) is a chiral diamine that plays a significant role in advanced organic chemistry, particularly in asymmetric synthesis and as a chiral ligand. NINGBO INNO PHARMCHEM, as a dedicated manufacturer and supplier, provides this vital compound with detailed specifications to ensure optimal performance.

The most notable physical characteristic of (1S,2S)-DPEN is its appearance: typically a white to light yellow solid or crystal powder. This visual cue is often the first indicator of its purity. Chemically, its molecular formula is C14H16N2, with a molecular weight of 212.29 g/mol. The compound's structure, featuring two phenyl groups attached to adjacent chiral carbon atoms, each bearing an amine group, dictates its behavior and utility.

A critical property is its optical activity, denoted by the negative sign in (1S,2S)-(-)-DPEN, indicating its levorotatory nature. This specific rotation is a direct consequence of its precise stereochemistry, with values around -102u00b0 in methanol. When you buy (1S,2S)-DPEN, ensuring a high enantiomeric excess (u226599% e.e.) is paramount. This high e.e. is what allows it to effectively induce chirality in synthetic reactions or act as a precise resolving agent.

Solubility is another important aspect; (1S,2S)-DPEN is generally insoluble in water but exhibits solubility in organic solvents like methanol and ethanol. This property influences its handling and reaction conditions. Furthermore, it is known to be sensitive to air, necessitating proper storage conditions, such as keeping it in a dry, sealed container, away from light, to maintain its integrity and purity over time. As a leading manufacturer, we adhere to strict quality control measures to ensure the stability and purity of every batch we supply.
