The Quad is threadbare pseudo-alliance specifically designed around containing China, period. India has long been friendly with Russia and is non-committal on the Ukraine situation and is apparently talking about "how to establish a rupee payment mechanism for trade with Russia to soften the blow of Western sanctions"[1]

It would be wise to assess how much the rest of the world is willing to go along with isolating Russia before we go in sanction-guns blazing and wind up isolating ourselves instead.
