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 Reference Standard
Certified saxitoxin reference standard is high-purity saxitoxin for analytical calibration, classified under HTS 2939.80.0010. As a chemically defined alkaloid, it fits Chapter 29 despite reference use, not excluded as diagnostic reagent.
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.
