## CPC

- C09B 23/166: {containing two or more nitrogen atoms (hydrazon dyes -CH=N-N- C09B26/02)}
- C07D 403/06: linked by a carbon chain containing only aliphatic carbon atoms
- C09B 23/0075: {the polymethine chain being part of an heterocyclic ring}
- C09B 23/02: the polymethine chain containing an odd number of >CH- {or >C[alkyl]-} groups
- C09B 23/06: three >CH- groups, e.g. carbocyanines
- C09B 23/08: more than three >CH- groups, e.g. polycarbocyanines
- C09B 23/083: {five >CH- groups}
- C09B 23/10: The polymethine chain containing an even number of >CH- groups {(styryl dyes C09B23/14, C09B23/14 takes precedence)}
- C09B 23/12: the polymethine chain being branched {"branched" means that the substituent on the polymethine chain forms a new conjugated system, e.g. most trinuclear cyanine dyes}
- C09B: ORGANIC DYES OR CLOSELY-RELATED COMPOUNDS FOR PRODUCING DYES {, e.g. PIGMENTS}; MORDANTS; LAKES (fermentation or enzyme using processes to synthesise a desired chemical compound C12P)
- C07D: HETEROCYCLIC COMPOUNDS (macromolecular compounds C08)
