Aliphatic Amines in Antarctic CR2, CM2, and CM1/2 Carbonaceous Chondrites Amines
> back to SiliaMetS Case Studies
Meteoritic water-soluble organic compounds provide a unique record of the processes that occurred during the formation of the solar system and the chemistry preceding the origins of life on Earth. Hence, molecular, isotopic, and enantiomeric compositions of amines in Antarctic carbonaceous chondrites were studied.
SiliaMetS DMT & SiliaBond Amine were used to purify the organic compounds from carbonaceous chondrites (scheme).
Results provided information on the prebiotic synthesis of amines and amino acids and on the origins of homochirality on Earth.

SiliaBond Amine (WAX) (R52030B)
SiliaBond Amine (Si-NH2) is an effective scavenger of acid chlorides, sulfonyl chlorides, isocyanates and other electrophiles. Si-NH2 has been shown to be effective metal scavenger and catalyst for Knoevenagel reactions. SiliaBond Amine is also used in chromatography as normal phase sorbent. -
SiliaMetS DMT (Dimercaptotriazine) (R79030B)
SiliaMetS DMT is the silica - bound equivalent of 2,4,6 - trimercaptotriazine (trithiocyanuric acid, TMT). It is a versatile metal scavenger for a variety of metals and the preferred metal scavenger for ruthenium catalysts and hindered Pd complexes. Best scavenger for: As, Ir, Ni, Os, Pd, Pt, Rh, Ru & Se. Good scavenger for: Cd, Co, Cu, Fe, Sc & Zn.
