This is a Notice of Intent for a sole source contract with Warner Graham LLP to supply Ethyl (ethanol) and Isopropyl Alcohol for NIH laboratories. The requirement is not set aside for small businesses, and performance will occur at the NIH Supply Center in Gaithersburg, MD. Delivery is required within 30 days after award, with a one-year period of performance including optional quantities. The justification for sole sourcing is that 90% of NIH labs use this specific brand, and switching vendors could compromise research consistency and data comparison. No budget amount is specified.
