Patent ID: 6936477

Claim:
A method of determining the structure of a compound, which comprises: a) providing a solid support on which a compound was synthesized by a reaction series comprising at least a first stage reagent and/or first stage reaction condition, and a second stage reagent and/or second stage reaction condition, wherein the first stage precedes the second stage in the reaction series, which solid support has attached thereto: i. a first identifier having a first tag, which tag comprises a code that records the first stage reagent or the first stage reaction condition; and ii. a second identifier having a second tag, which tag comprises a code that records the second stage reagent or the second stage reaction condition; b) detaching the first tag and the second tag from the solid support such that a mixture of soluble tags is formed; c) reacting the mixture of tags with a labeling reagent which introduces a detectable component to each tag; d) detecting each tag via its detectable component; e) determining the identity of each of the detected tags from step (d), whereby the identities of the reagents and/or reaction conditions of the first and second stages of the reaction series are determined: and f) deriving the structure of a compound from the identities of the detected tags.
