Scopolamine Methyl Nitrate from TCI, product code S0230, is also known as methscopolamine nitrate. It is a quaternary ammonium derivative of scopolamine, a tropane alkaloid found naturally in plants of the Solanaceae family. Methylation at the nitrogen atom converts scopolamine into a quaternary cation, which is paired with a nitrate anion. In the laboratory, this compound serves as a biochemical and pharmacological reagent. Its main use is as a muscarinic acetylcholine receptor antagonist in research on the autonomic nervous system.
The key feature of Scopolamine Methyl Nitrate is the permanent positive charge on its quaternary nitrogen. This charge makes the molecule highly polar, so it has difficulty crossing the blood-brain barrier. Its parent compound, scopolamine, acts strongly on the central nervous system, so the two behave quite differently. Researchers use this difference to separate peripheral antimuscarinic effects from central effects when designing experiments. Because TCI supplies it as an alkaloid of defined purity, the compound is also a useful reference material for developing analytical methods for tropane compounds.
In Indonesia, this reagent is relevant to pharmacology laboratories in faculties of pharmacy and medicine, neuroscience research laboratories, and analytical laboratories that work with natural products and alkaloids. Academic researchers can use it in teaching and research on cholinergic pharmacology, and analytical teams can use it to build and check methods for tropane alkaloids. As a TCI product supplied through AMI Scientific, it suits institutions that need a well-identified alkaloid reagent from an established manufacturer for reproducible experimental work.

- Muscarinic receptor antagonism studies: the compound blocks muscarinic acetylcholine receptors, so it is a suitable tool for studying how cholinergic signalling works in experimental models of the autonomic nervous system.
- Separating peripheral and central effects: its permanent charge limits passage across the blood-brain barrier, so researchers can tell peripheral antimuscarinic actions apart from central actions when comparing it with scopolamine.
- Autonomic nervous system research: it acts mainly on peripheral muscarinic receptors, which makes it useful for studies of the parasympathetic control of organs and tissues in pharmacology laboratories.
- Analytical method development for tropane alkaloids: as a TCI alkaloid of defined purity, it can serve as reference material when developing and checking chromatographic or other analytical methods for tropane compounds.
- Teaching in cholinergic pharmacology: pharmacy and medical faculties can use it to show students how a quaternary derivative changes a parent alkaloid's polarity, distribution, and pharmacological profile.
