It is the second time he has lost his police job after being reinstated, when his original conviction was quashed and a retrial ordered.
His sacking, which was announced today, became a formality following his conviction and jailing in February for misconduct and perverting the course of justice.
A spokesman for Scotland Yard said he had been dismissed with immediate effect after a Tribunal found he had failed to meet the appropriate standards of conduct.
Dizaei spent 27-years with the force, but in 2010 was jailed after being convicted of framing Iraqi businessman Waad al-Baghdadi, following a row outside a restaurant
A year later he was freed by the Court of Appeal, but was convicted for a second time following a retrial.
Deborah Glass, IPCC Deputy Chair said: "Ali Dizaei's dismissal from the Metropolitan Police Service was the right and inevitable outcome following his conviction, a second time, for serious criminal offences.
"There is no place in the police for corrupt officers and they have no business wielding the powers of a police officer in our communities.
"Many will wonder how Mr Dizaei was able to rise to the very senior rank of commander. The Metropolitan Police Service needs to ensure that never again is its reputation so badly damaged by the acts of one of its most senior officers."
A spokesman for Dizaei said he would continue to fight to clear his name and was scheduled to bring tribunal proceedings for unfair dismissal against the MPS next February.
His spokesman added: "He has been down this road before where he was prematurely dismissed from the force in 2010 when there was a live appeal against his conviction".
He said: "He notes with interest how the Met remained silent when he won his appeal and was reinstated last year and today the MPS (Metropolitan Police Service) department of public affairs is busy shouting his dismissal from rooftops to the media.
"There is (an) ongoing appeal against his conviction and Dr Dizaei has issued employment tribunal proceedings against the MPS with regard to his treatment scheduled to be heard in February 2013."
