Another advantage is lossless interconversion with other serialization formats. The line notation InChI might appear to compete with Balsa in this sense. The authors of InChI have noted that InChI is not a solution to the molecular serialization problem but rather an identifier . The reason presumably lies with the fact that InChI uses concepts such as hydrogen delocalization that are uncommon elsewhere. To date, no third-party reader or writer of InChI has been reported.
