More Information
Summary:A novel nonsolvate-form crystal of polymethine compound is provided which has good stability in solution, shows a high gram extinction coefficient, is excellent in storage stability, is easy to handle and is highly sensitive to general-purpose semiconductor lasers. Thus is provided a nonsolvate-form crystal of polymethine compound of the formula (I) given below as well as a process for producing the nonsolvate-form crystal of polymethine compound of formula (I) which comprises reacting a polymethine ether compound of the formula (II) given below with hydrochloric acid or hydrobromic acid. (In the above formula, X represents Cl or Br.) (In the above formula, R represents an alkyl group, an alkoxyalkyl group or an optionally substituted aryl group.)
