Saxitoxin Hydrochloride

Saxitoxin hydrochloride is the salt form of saxitoxin, a naturally occurring paralytic shellfish toxin classified as an alkaloid under HTS 2939.80.0010. It is chemically defined and falls within Chapter 29's scope for separate organic compounds, specifically saxitoxin.

Synthetic Saxitoxin

Synthetic saxitoxin is a laboratory-reproduced version of the natural paralytic alkaloid toxin, explicitly covered under HTS 2939.80.0010 as alkaloids reproduced by synthesis. Its chemical structure matches natural saxitoxin, qualifying it as a separate chemically defined organic compound.

Saxitoxin Sodium Salt

Saxitoxin sodium salt is the sodium derivative of saxitoxin, classified under HTS 2939.80.0010 as an alkaloid salt per Chapter 29 note 3(C)(1). Inorganic salts of organic alkaloid compounds remain with the parent organic compound classification.

Saxitoxin in Aqueous Solution

Saxitoxin dissolved in water for stability during transport falls under HTS 2939.80.0010 per Chapter 29 note 2(d). The aqueous solution qualifies as a normal transport method without rendering it for specific use.

Saxitoxin with Stabilizer

Saxitoxin containing added stabilizers necessary for preservation falls under HTS 2939.80.0010 per Chapter 29 note 2(f). Stabilizers don't change its nature as a chemically defined alkaloid.

dc-Saxitoxin Derivative

dc-Saxitoxin (decarbamoyl saxitoxin) is a derivative of saxitoxin classified under HTS 2939.80.0010 as an alkaloid derivative. As a chemically defined structural analogue of saxitoxin, it remains in the specific saxitoxin subheading.
