SDB-005 (also known as NA-PINAC using systematic EUDA nomenclature)[1] is an indazole-based synthetic cannabinoid that has been sold online as a designer drug.

SDB-005 is the indazole core analog of PB-22 where the 8-hydroxyquinoline has also been replaced with a naphthalene group.

The code number SDB-005 was originally used for a different compound, the N-phenyl instead of N-benzyl analogue of SDB-006.

[3] However, SDB-005 was subsequently used as the name for the indazole-3-carboxylate compound mentioned above when it was sold in Europe as a designer drug, and was entered into the EMCDDA synthetic drug database under this name.

[4] Consequently, there are now two distinct, yet fairly closely related cannabinoid compounds, which may both be referred to under the code SDB-005.
