Abdul Shokur Ezedi was seen on CCTV at a Tesco Express in north London about 70 minutes after the attack.
A body found in the Thames this week has been officially identified as chemical attack suspect Abdul Shokur Ezzedi, the Metropolitan Police has announced.
Officers began searching for Mr Ezzedi, 35, after the attack on a woman and two girls in Clapham on January 31.
Ezzedi was last seen on a surveillance camera leaning over London’s Chelsea Bridge.
An autopsy conducted on Wednesday confirmed his cause of death was drowning.
Police said Ezzedi’s family has been kept updated on the situation and the file will be passed to the coroner.
Detective Inspector John Savel of the Metropolitan Police said work was being carried out to formally identify Ezzedi “as soon as possible”.
“As the public expected, our investigation into this brutal attack continues,” he added.
Ezzedi, from the Newcastle area, is accused of dousing his ex-partner with alkali and injuring two young children, aged eight and three, in Clapham.
CDR Sabel said the 31-year-old woman was still in hospital, “in a stable condition and no longer sedated.”
Police believe Ezedi fled the scene after the attack, initially using a bank card to get on the Tube, then walking along a wide-ranging route bordering the banks of the Thames.
Investigators pieced together surveillance camera footage to prove that he jumped into the river.
Marine police units carried out a low-tide search and recovered the body at Tower Pier, near Tower Bridge, on Monday.
An autopsy was conducted at Poplar Mortuary on Wednesday, and Ezzedi’s body was officially identified on Thursday, the Metropolitan Transportation Authority added.

They argue that a broken relationship may have been his motive.
His car was discovered in Streatham, south London, at 7pm. About 25 minutes later, the attack occurred inside a car in Lesser Avenue, Clapham, in which a “very strong and concentrated corrosive substance” was used.
