This federal contract award was issued by the Centers for Disease Control and Prevention (CDC) Office of Acquisition Services to Sigma-Aldrich, Inc., a leading life science and high technology company. The $146,395 firm fixed price purchase order is for the delivery of various laboratory supplies, chemicals, and materials to support scientific research and development across multiple federal agencies. Sigma-Aldrich, a foreign-owned, for-profit organization, has established itself as a key supplier of critical research enablers to government laboratories and research institutions through its diverse product portfolio and history of federal contract awards. This contract is not set aside and represents one of several indefinite delivery vehicles (IDVs) held by Sigma-Aldrich, including a $315,000 single-award contract with the Defense Health Agency and a $200 million multiple-award ID/IQ contract with the Federal Emergency Management Agency to support COVID-19 testing efforts. The company has also fulfilled small business set-aside contracts in the past, demonstrating its capacity to serve as both a prime contractor and subcontractor for defense and civilian agency projects.
