화재 위험	Special Hazards of Combustion Products: None· HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames.Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. Vapour/air mixtures are explosive. Risk of fire and explosion on contact with oxidizing agents.
화재 가능성	FlammableA very dangerous fire hazard when exposed to heat, flame, or oxidiziers.
건강 유해성	Breathing of vapor causes pulmonary irritation, delayed gastro-intestinal irritation, tremors, and convulsions. Contact with skin or mucous membranes causes chemical burns. Can be absorbed through skin to cause systemic intoxication and convulsions. (USCG, 1999)· TOXICmay be fatal if inhaled, ingested or absorbed through skin.

용도

1,2-Dimethylhydrazine (SDMH) unlike its analog 1,1- dimethylhydrazine (UDMH) is used only in small quantities as a research chemical. There are no known commercial uses, although it was evaluated as a high-energy rocket fuel. The material is a fuming, strongly alkaline, moderately volatile liquid.

일반 설명

A colorless liquid with an ammonia-like odor. Less dense than water. Flash point is 5°F. Contact irritate skin, eyes, and mucous membranes. Very toxic by ingestion, inhalation and skin absorption. Used to make photographic chemicals.
