Monomethylhydrazine (MMH, CAS: 60-34-4) Specifications & Chemical Architecture

Engineered for high chemical hypergolic reactivity, extreme chemical purity, and minimum metallic contaminants to meet aerospace and fine organic synthesis tolerances.

Information Gain Insight: Methyl hydrazine (CH₆N₂), functionally known as Monomethylhydrazine (MMH), operates as a volatile liquid hydrazine analog characterized by a single methyl radical substituent. When deployed in hypergolic bipropellant systems alongside dinitrogen tetroxide (N₂O₄ / MON-3), MMH features superior thermal stability over anhydrous hydrazine while retaining high theoretical specific impulse, minimal freezing risk (-52.4°C), and immediate auto-ignition without catalytic delay.

Frequently Asked Questions on Methyl Hydrazine Procurement

Key information regarding technical specifications, transport safety, minimum orders, and supply chain verification.

What are the essential packaging protocols used by Chinese suppliers for Methyl Hydrazine?
Due to its dual designation as a flammable liquid and high-toxicity hazard (UN 1244, Class 6.1 with sub-risks 3 and 8), Methyl Hydrazine is packed exclusively in UN-certified heavy-gauge 1A1 stainless steel closed-head drums or specialized IMO Type 1 / DOT 51 ISO tanks. All shipping containers are thoroughly pickled, passivated, and pressurized under ultra-dry nitrogen before filling to eliminate any ambient air or moisture contamination.
How does Monomethylhydrazine (MMH) compare against Anhydrous Hydrazine and UDMH?
Compared to pure Hydrazine (N₂H₄), MMH possesses a significantly lower freezing point (-52.4°C vs. +2°C), eliminating the necessity of active heating systems in extraterrestrial conditions. Compared to Unsymmetrical Dimethylhydrazine (UDMH), MMH offers higher specific impulse and greater fluid density, allowing for reduced tankage weight in satellites and upper-stage space propulsion applications.
What export licenses are required to procure Methyl Hydrazine from China?
Methyl Hydrazine is subject to Dual-Use export controls due to its utility in rocketry and defense propulsion. Buyers must provide a verified End-User Certificate (EUC) and an authorized Import Permit (where mandated by the recipient nation). China's Ministry of Commerce (MOFCOM) processes the application, typically taking 4 to 8 weeks for final export clearance.
What is the shelf life and storage recommendation for propellant-grade MMH?
When kept inside its original hermetically sealed, passivated 316L stainless steel container beneath an unbroken nitrogen blanket (gauge pressure > 0.3 bar), propellant-grade MMH has a shelf stability exceeding 5 years. It must be housed in a fireproof, well-ventilated Class A chemical warehouse kept between 0°C and 30°C, strictly away from oxidizing agents and active catalytic metals.
Can customized purity levels be formulated for pharmaceutical applications?
Yes. Beyond standard technical and propellant grades, custom production runs with reduced water content (< 0.5% w/w) or ultra-low heavy metal concentrations can be provided alongside comprehensive batch COA analysis via Gas Chromatography-Mass Spectrometry (GC-MS) and ICP-MS testing.
