Mallinckrodt® Chemicals brand name to change as Avantor™ (formerly Mallinckrodt Baker)

continues transition following recent acquisition by affiliate of New Mountain Capital

Phillipsburg, New Jersey – Avantor Performance Materials announced

today that it is renaming its Mallinckrodt® Chemicals brand product line Macron™ Chemicals, as

the company transitions away from its former Mallinckrodt Baker identity.

The name change, which will be implemented on March 7, 2011, will not involve any product or

manufacturing changes.

Avantor will follow its standard Management of Change (MOC) procedure for this change. While

the change will not impact product functionality, customers of record will receive notification of the

change. The timing of the announcement gives Avantor customers time to prepare to accept

product under the new brand name on March 7, 2011.

Avantor, formerly Mallinckrodt Baker, manufactures and markets high-performance chemistries

and materials around the world under two well-known and respected brand names, J.T.Baker® and

Mallinckrodt® Chemicals, now to be called Macron™ Chemicals. These products are widely used in

biotechnology and pharmaceutical production; microelectronics and photovoltaic manufacturing;

and in research, academic and quality control laboratories.

Headquartered in Phillipsburg, New Jersey (USA), Avantor was acquired from Covidien in August

2010 by an affiliate of New Mountain Capital, a New York-based private equity firm.

Under the terms of the acquisition agreement, the Mallinckrodt® name will remain with Covidien.

Products sold by Avantor under the Mallinckrodt® Chemicals brand name will continue to be

manufactured and marketed by Avantor but will now be called Macron™ Chemicals. Avantor

intends to continue using the J.T.Baker® brand name.

The Macron™ Chemicals product line will be identical to the current Mallinckrodt® line, which

includes high-purity solvents, acids, solutions, salts, minerals and sugars.

Paul Smaltz, Vice President of Global Marketing at Avantor, said the company’s products have a

long history of use in laboratories, as well as in the demanding pharmaceutical market – a factor

that contributed to the selection of the new Macron™ brand name.

“Our products have a legacy of safety and trust, with a 140-year tradition for delivering the highest

standards of quality, purity and consistency,” explained Smaltz. “The Macron™ Chemicals name

embodies size and strength, setting a standard of consistency recognized across the industry and

around the world. Today, the brand’s focus is on providing products for cGMP pharmaceutical

production and everyday laboratory use in environmental testing, university research and industrial

manufacturing,” he said.

Smaltz emphasized that the Mallinckrodt® brand name is changing, but not the company’s

manufacturing process.

“Our Macron™ brand products will be produced in the same facilities under the same

manufacturing processes, and will share the same product numbers, product names and code

numbers as the previous Mallinckrodt® brand products,” said Smaltz. “We don’t anticipate any

supply interruptions because of this change and we will continue to deliver high-quality, high-purity

materials with the consistency and reliability our customers expect from us.”
