Document Type and Number:
WIPO Patent Application WO/2013/051414
Kind Code:
A1
Abstract:
The present invention pertains to: compounds represented by formula (A) or (B), which enable the red color of pyrroloquinoline quinine (PQQ) to be improved and enable the original functions of PQQ to be obtained, and salts thereof; and a method for efficiently producing said compounds. (In the formula, R is an alkyl group, a hydroxyalkyl group, a dihydroxyalkyl group, or an alkoxyalkyl group.)
