Due to its toxic nature, vinyl chloride is not found in other products. Poly(vinyl chloride) (PVC) is very stable, storable and not toxic. [2] Until 1974, vinyl chloride was used in aerosol spray propellant. [7] Vinyl chloride was briefly used as an inhalational anaesthetic, in a similar vein to ethyl chloride, though its toxicity limited this use.
Molded PVC is used to produce phonograph, or "vinyl," records. PVC piping is a cheaper alternative to metal tubing used in musical instrument making; it is therefore a common alternative when making wind instruments, often for leisure or for rarer instruments such as the contrabass flute.
Chemicals on the red list may not be included in materials used in construction that seeks to meet the criteria of the Living Building Challenge (LBC).

Vinyl polymers are subject of several structural variations, which greatly expands the range of polymers and their applications. With the exception of polyethylene, vinyl polymers can arise from head-to-tail linking of monomers, head-to-head combined with tail-to-tail, or a mixture of those two patterns. Additionally the substituted carbon center in such polymers is stereogenic (a "chiral center")
