This is one of two items that can be used to reduce the price of upgrading your ships engines. The chemicals are found as a reward during the side quest "Fourth Law of Robotics: Destoying Warehouses it's OK, go for it!". The quest needs to be completed quickly in order to recieve the chemicals. The chemicals you get from the quest need to be identified, requiring you to pay 200C at the Hospital on Europa 4. The chemicals give you a 1000C discount on engine upgrades, giving you a 800C net saving after accounting for the cost to identify them.
