For professionals in the chemical and pharmaceutical industries, a deep understanding of a compound's properties is crucial for successful procurement and application. (1R,2R)-(-)-1,2-Diaminocyclohexane (CAS 20439-47-8) is a highly valued chiral intermediate, and knowing its characteristics ensures optimal usage. As a leading manufacturer and supplier based in China, we provide essential data to help purchasing managers and R&D scientists make informed decisions when they decide to buy this critical compound.

Chemically, (1R,2R)-1,2-Diaminocyclohexane has the molecular formula C6H14N2 and a molecular weight of approximately 114.19 g/mol. This structure features two amine groups positioned in a trans configuration on a cyclohexane ring, with a specific R,R configuration at the chiral centers. This precise stereochemistry is what confers its significant value in chiral synthesis. Its chemical reactivity stems from the nucleophilic nature of the amine groups, allowing it to participate in a wide array of reactions.

Physically, the appearance of (1R,2R)-1,2-Diaminocyclohexane can range from an off-white solid to a pale-yellow oil, depending on its exact purity and handling. The provided melting point is typically between 41-45 °C, indicating it's a solid at standard room temperatures. The boiling point is reported around 193.6 °C at atmospheric pressure, signifying its relatively low volatility. These physical properties are important considerations for storage, handling, and transportation, especially for bulk purchases.

A key specification for buyers is the purity, which is commonly guaranteed to be 99% minimum. This high purity is essential when using it as a pharmaceutical intermediate, especially for the synthesis of complex APIs like oxaliplatin. Enantiomeric purity, often expressed as enantiomeric excess (e.e.), is also a critical parameter, typically required to be above 95% to ensure the stereochemical integrity of downstream products. Our manufacturing process in China is optimized to achieve and verify these stringent quality standards for every batch.

Furthermore, understanding its solubility is important for formulation and reaction design. It is generally soluble in water and common organic solvents like methanol and chloroform, although specific solubility can vary. It's also noted to be air-sensitive and incompatible with strong oxidizing agents, necessitating proper storage in sealed containers under an inert atmosphere in a cool, dry place.
