ASAS is able to isolate and purify C13H23Br (Br-C13 rubber oligomer).
New >>>>> The rubber oligomer Br-C21, formula C21H39Br is now also available <<<<<<<< NEW
These compounds are of special interest, due to their abundance in rubber extracts and their toxicological properties. Contradictory information are available regarding the mutagenicity (AMES test negative, modified AMES test positive). The reactivity towards proteins, as predicted with in-silico tools (Toxtree protein binding) was confirmed experimentally.
As an economic alternative to purchasing the neat compounds, ASAS offers stock solutions,
e.g. 1 mg/ml in heptane, 1ml, 395 EUR net.
ASAS is the only laboratory world-wide (at least to our knowledge), offering these compounds.
An example of an CoA can be found here: BrC13-Oligo-CoA-#20180724
Information on degraded antioxidants: BHT quinone methide
