1,1-Dimethylhydrazine Specification

The IUPAC name of this chemical is 1,1-dimethylhydrazine. With the CAS registry number 57-14-7 and EINECS 200-316-0, it is also named as Dimethylhydrazine unsymmetrical. The classification codes are Mutation data; Reproductive Effect; Tumor data. It is clear colorless liquid with an ammonia-like odor which is miscible with water, ethanol, and kerosene. It turns yellowish on exposure to air and absorbs oxygen and carbon dioxide. Moreover, this chemical is a powerful reducing agent and can exhibit high acute toxicity as a result of exposure by all routes. When heated to decomposition it emits highly toxic fumes of NO_x. In addition, 1,1-Dimethylhydrazine should be sealed in the container and stored in the cool and dry place which must be away from oxidant and acids.

The other characteristics of this product can be summarized as: (1)ACD/LogP: -1.28; (2)# of Rule of 5 Violations: 0; (3)ACD/LogD (pH 5.5): -3.85; (4)ACD/LogD (pH 7.4): -2.16; (5)ACD/BCF (pH 5.5): 1; (6)ACD/BCF (pH 7.4): 1; (7)ACD/KOC (pH 5.5): 1; (8)ACD/KOC (pH 7.4): 1; (9)#H bond acceptors: 2; (10)#H bond donors: 2; (11)#Freely Rotating Bonds: 1; (12)Polar Surface Area: 6.48 Å²; (13)Index of Refraction: 1.426; (14)Molar Refractivity: 18.57 cm³; (15)Molar Volume: 72.4 cm³; (16)Polarizability: 7.36×10^-24 cm³; (17)Surface Tension: 27.8 dyne/cm; (18)Density: 0.829 g/cm³; (19)Flash Point: 1.1 °C; (20)Enthalpy of Vaporization: 30.6 kJ/mol; (21)Boiling Point: 63.9 °C at 760 mmHg; (22)Vapour Pressure: 168 mmHg at 25°C.

Preparation of 1,1-Dimethylhydrazine: It can be obtained by the reaction of ammonia, ammonium chloride and dimethylamine. First, we can get chloro amine by ammonia and sodium hypochlorite. Secondly, the reaction of chloro amine and dimethylamine aqueous solution can generate UDMH solution. Finally, after a series of treatment, we can get the product.
NH₃+NaOCl→NH₂Cl+NaOH
NH₂Cl+HN(CH₃)₃+NaOH→(CH₃)₂NNH₂+NaCl+H₂O

Uses of 1,1-Dimethylhydrazine: It is often used in hypergolic rocket fuels as a bipropellant in combination with the oxidizer nitrogen tetroxide and less frequently with IRFNA (red fuming nitric acid) or liquid oxygen. It is also used in the production of plant growth regulator. What's more, this chemical is used as fuel additive and used in organic synthesis. In addition, it can react with pyridine-3-carbaldehyde to get pyridine-3-carbaldehyde-dimethylhydrazone. This reaction needs solvent ethanol by heating on a steam bath. The reaction time is 30 min. The yield is 77%.

1,1-Dimethylhydrazine can react with pyridine-3-carbaldehyde to get pyridine-3-carbaldehyde-dimethylhydrazone

When you are using this chemical, please be cautious about it as the following:
It is highly flammable and can cause burns and cancer. What's more, it is toxic by inhalation and if swallowed. And it is also toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment. In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible.) So it should avoid exposure - obtain special instructions before use and avoid release to the environment. Refer to special instructions / safety data sheets.

People can use the following data to convert to the molecule structure.
1. SMILES:N(N)(C)C
2. InChI:InChI=1/C2H8N2/c1-4(2)3/h3H2,1-2H3
3. InChIKey:RHUYHJGZWVXEHW-UHFFFAOYAL
