4-Vinylcyclohexene (4-VCH)

A pyrolysis product of styrene-butadiene rubber (SBR) carpet backing, appearing at m/z 108 in the GC-MS. Elevated m/z 108 in a fire debris extract is a strong indicator of SBR pyrolysis contribution and a caution against classifying the aromatic fraction as petroleum product.
