A carrier for use for separation purpose and a method for separation of a compound enable a chemical reaction to be performed in a liquid phase, a compound of interest to be separated from the liquid phase after the completion of the reaction readily, the separated compound to be evaluated by structural analysis or the like while the compound is being bound to the carrier, and the compound to be separated from the carrier readily. A carrier for separation is also provided which has a reaction site capable of reacting with other compound(s) on a benzene ring, and a long-chain group having a specified carbon atom(s) at each of the ortho-position and the para-position of the reaction site through an oxygen atom.

Peptides may be continuously produced by a method including the following steps (1), (A), (2), and (B):
(1) performing a condensation reaction in a flow reactor to obtain an N-protected C-protected peptide in which an N-terminal amino group and C-terminal are protected by protecting groups, a side chain functional group is optionally further protected by a protecting group, and at least one of the C-terminal or the side chain functional group is protected by a pseudo-solid-phase protecting group (N-protected C-protected peptide),
(A) washing a reaction mixture containing an N-protected C-protected peptide in a flow reactor and separating oil and water to separate an organic layer containing the N-protected C-protected peptide,
(2) subjecting an organic layer containing an N-protected C-protected peptide to a reaction to remove a protecting group of an N-terminal amino group in a flow reactor to obtain a C-protected peptide in which an N-terminal amino group is not protected, C-terminal is protected by a protecting group, a side chain functional group is optionally further protected by a protecting group, and at least one of the C-terminal or the side chain functional group is protected by a pseudo-solid-phase protecting group (N-unprotected C-protected peptide),
(B) subjecting a reaction mixture containing an N-unprotected C-protected peptide to washing and oil-water separation in a flow reactor to separate an organic layer containing the N-unprotected C-protected peptide.
