Avantor Performance Materials Officially Changes Mallinckrodt Chemicals Product Name to Macron Chemicals

Macron Chemicals Name Change Now in Effect, Replacing Products Formerly Known as Mallinckrodt Chemicals


PHILLIPSBURG, NJ--(Marketwire - March 8, 2011) - Avantor™ Performance Materials (formerly Mallinckrodt Baker) announced today that its Mallinckrodt® Chemicals product brand name has officially changed and will now be referred to as Macron™ Chemicals.

Avantor first announced its intent to change the Mallinckrodt® Chemicals product name on November 15, 2010 and has worked with customers to inform them over the past several months under the company's standard Management of Change (MOC) procedure.

Avantor manufactures and markets high-performance chemistries and materials around the world under two well-known and respected brand names, J.T.Baker® and Macron Chemicals (formerly Mallinckrodt® Chemicals). These products are widely used in biotechnology and pharmaceutical production; electronics and photovoltaic manufacturing; and in research, academic and quality control laboratories.

The changeover involves only the product brand names. The Macron product line is identical to Avantor's former Mallinckrodt® line, which includes high-purity solvents, acids, solutions, salts, minerals and sugars. Although the product brand name is changing, the quality system and manufacturing process will remain the same. Macron brand products are produced in the same facilities and share the same product numbers, product names and lot numbering system as the previous Mallinckrodt® brand products.

"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 Avantor's Vice President of Global Marketing, Paul 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 added that while the company has officially implemented the name change, it is possible for customers to receive product with Mallinckrodt® labels, certificates of analysis and other documentation for a period of time as product works its way through the supply chain.
