Cyclohexanecarbohydrazide

China [CN]

Physical and Chemical Properties

Appearance: Typically a white crystalline powder or solid, with regular crystals at high purity.

Solubility: Due to the presence of a polar hydrazide group (-CONHNH₂), it is expected to be soluble in polar solvents such as water, methanol, and ethanol, but poorly soluble in non-polar solvents such as ether and n-hexane.

Stability: The hydrazide structure (-NHNH₂) exhibits some reducing properties and is relatively stable at room temperature. However, it should be protected from strong oxidizing agents. For long-term storage, it is recommended to keep the product sealed, protected from light, and stored in a cool, dry place.

Chemical Properties

Reactivity of the Hydrazide Group:

As a hydrazide (R-CO-NH-NH₂), it can undergo condensation reactions with aldehydes and ketones to form hydrazone compounds (R-CO-N=N-R'). This property makes it useful for the identification or derivatization of carbonyl compounds.

The amino group (-NH₂) in the hydrazide group is alkaline and reacts with acids to form salts, increasing its water solubility. It has reducing properties and can be oxidized (e.g., by reactions with hydrogen peroxide, potassium permanganate, etc.), potentially converting itself into azo compounds or other oxidation products.

Characteristics of the cyclohexane ring:

The cyclohexane ring is a saturated alicyclic structure with high chemical stability. It is not susceptible to substitution or oxidation reactions at room temperature. Under strong conditions (e.g., high temperature, strong acid), it may undergo ring-opening or substitution reactions, but its activity is relatively low.
