Regulatory evidence across markets

None of the 13 markets tracked here holds an imported rule under the name HEXYL AMINOLEVULINATE HCl.

That is a statement about this inventory, not about the law: no imported rule is not evidence that a substance is permitted. A rule may exist under a different name, under a CAS or EC number this glossary entry does not carry, or in a dataset not yet imported.

Hexaminolevulinate Hydrochloride

Hexaminolevulinate Hydrochloride is the hydrochloride salt form of hexaminolevulinate, a hexyl ester of the heme precursor 5-aminolevulinic acid (ALA) with potential photosensitizing activity. Hexaminolevulinate serves as a precursor of photoactive porphyrins (PAPs), particularly protoporphyrin IX (PpIX), which selectively accumulate in rapidly proliferating cells, such as those seen in tumor tissue. When exposed to blue light, PAPs are activated and emit red light thereby allowing tumor imaging. — NCI Thesaurus (NCIt)
