Scopolamine Methyl Bromide from TCI, product code S0231, is also known as methscopolamine bromide. It is a quaternary ammonium salt of scopolamine with a bromide anion. Scopolamine is a tropane alkaloid found in plants of the Solanaceae family, and methylating its nitrogen atom produces a cation with a permanent charge. In the laboratory, this compound is used as a biochemical reagent in pharmacological research, mainly as a muscarinic acetylcholine receptor antagonist that acts mostly on peripheral tissues.
The permanent positive charge on the quaternary nitrogen makes Scopolamine Methyl Bromide highly polar, so it does not readily cross into the central nervous system. Researchers choose it for this reason when they want to block muscarinic receptors in peripheral organs without the strong central effects of scopolamine itself. The bromide is the best-known salt of this compound in the pharmacological literature, more so than the nitrate. That makes reference data easier to find when researchers design and compare their experimental protocols.
In Indonesian laboratories, this reagent is relevant to pharmacology researchers in faculties of pharmacy and medicine, and to related life science research groups. These teams study the cholinergic system, peripheral receptor pharmacology and the differences between central and peripheral drug action. Because the TCI product code S0231 and the CAS number 155-41-9 are clearly stated, procurement staff and researchers can match the reagent to their protocols, literature references and internal documentation.

- Muscarinic receptor antagonism studies: As a muscarinic acetylcholine receptor antagonist, the compound lets researchers block cholinergic signalling and study how receptors respond in experimental systems.
- Peripheral versus central pharmacology comparisons: Its limited penetration into the central nervous system makes it a useful comparator to scopolamine when separating peripheral effects from central ones.
- Peripheral organ pharmacology research: Its permanently charged, highly polar structure suits experiments that aim to block muscarinic receptors in peripheral organs without strong central effects.
- Cholinergic system research: Researchers studying acetylcholine signalling pathways can use this well-characterised tropane alkaloid derivative to probe how muscarinic receptors are involved in physiological responses.
- Protocol development and literature-based comparison: The bromide is the most widely documented salt form, so researchers can compare their results with published pharmacological data when designing experimental protocols.
