ASAS is able to isolate and purify the bromo rubber oligomers C13H23Br (Br-C13 rubber oligomer) and

C21H39Br (Br-C21 rubber oligomer).

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.

The butyl rubber oligomer C21H40 (CAS 114123-73-8) is also available.

ASAS is the first 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
