1,1-Dimethylhydrazine
Product Name: 1,1-Dimethyl Hydrazine
CAS: 57-14-7
Molecular formula: C2H8N2
Formula Weight: 60.1
Description:
Dissymmetric dimethylhydrazine (UDMH) (1,1-dimethylhydrazine) is a volatile toxic, hygroscopic liquid with a strong clear, fish-like, ammoniacal odor that is typical of organic amines. It is yellowish when exposed to air and absorbs oxygen and carbon dioxide.
UDMH is often used in hyperpolar bipropellant rocket fuels only in combination with the oxidizing agent and nitrogen tetroxide less frequently with IRFNA (red fuming nitric acid) or liquid oxygen. UDMH is a derivative of hydrazine, and is sometimes called hydrazine. As fuel in specification MIL-D-25064 is described.

Calcium formate price
Produktname: Calcium formate
CAS: 544-17-2
Summenformel: C2H2CaO4
Formel Gewicht: 130.11
Beschreibung:
Calciumformiat, Ca (HCOO) 2, ist das Calciumsalz von Ameisensäure, HCOOH. Es ist auch bekannt als Lebensmittelzusatzstoff E238 in der Lebensmittelindustrie. Die mineralische Form ist sehr selten und heißt formicait. Es ist aus wenigen Borablagerungen bekannt. Es kann synthetisch hergestellt werden, indem man Calciumoxid oder Calciumhydroxid mit Ameisensäure umsetzt.
