Antioxidant 2246 (2,2′-methylenebis(4-methyl-6-tert-butylphenol)), CAS 119-47-1, is a hindered phenolic antioxidant used to protect rubber and plastics against heat and oxygen ageing. As a bis-phenol it is non-staining and non-discolouring, so it suits light-coloured and bright compounds as well as general rubber goods. PolyBlueChem supplies it to the specification below, with per-batch COA and SDS and competitive pricing on bulk volumes.
