It is proved a purity theorem for quadratic spaces over semi-local regular integral domain containing a field of odd characteristic. This theorem extends to the semi-local case the corresponding results proven previously by the author and by the author jointly with K. Pimenov. To get this result we extend the purity theorem of Ojanguren–Panin to this more general setting.
