Description
Hexamethonium bromide is a peripherally-acting nondepolarizing neuromuscular blocking agent that functions as an antagonist of nicotinic acetylcholine receptors (nAChRs). It is known for its ability to decrease acetylcholine release and lower mean arterial pressure, as well as induce signs of nicotine abstinence in nicotine-dependent rats. Historically, formulations containing hexamethonium bromide were utilized in the treatment of hypertension.
Uses
Used in Autonomic Ganglia Research:
Hexamethonium bromide is used as an autonomic ganglia-blocking agent for studying its effects on whisker movement in rats. This application aids in understanding the role of autonomic ganglia in motor control and neurological functions.
Used in Nicotinic Receptor Research:
In the field of nicotinic receptor research, hexamethonium bromide serves as a nicotinic receptor antagonist, enabling the study of its impact on antigen-induced arthritis (AIA) progression in mice. This helps researchers to explore the potential therapeutic effects of hexamethonium bromide in managing inflammatory conditions.
Used in Cardiovascular Response Studies:
Hexamethonium bromide is utilized as a non-selective ganglionic nicotinic acetylcholine receptor (nAChR) antagonist in studies examining its effects on cytisine-induced autonomic cardiovascular responses in mice. This application is crucial for investigating the drug's influence on the cardiovascular system and its potential use in treating related conditions.

Bistrium,Squibb,US,1951
Manufacturing Process
Hexamethylene diamine (116 g), sodium carbonate (466 g), and water (800
ml) were heated to 60°C, and dimethyl sulfate (830 g) added with stirring
over 1% hours keeping the temperature below 90°C. The reaction mixture
was then stirred at 90°C for 2 hours, then cooled to 20°C, acetone (1,200 ml)
added and the whole cooled to 0°C.
The solid formed was removed by filtration and washed with acetone (150
ml). Filtrate and washings were diluted with water to 4 liters and heated to
60°C under reflux. To this was added a solution prepared from embonic acid
(388 g), sodium hydroxide (80 g) and water (5 liters), the whole refluxed for
10 minutes and thereafter allowed to cool overnight.
The resultant embonate (530 g) was filtered off, washed twice with a solution
of acetone (75 ml) in water (425 ml), and dried at 100°C to give an
amorphous yellow powder, MP 290°C to 291°C (with decomp.). 588 g of the
embonate was dissolved in boiling water (4 liters).
Hydrobromic acid 50% w/w (325 g) diluted with water (2 liters) was added
slowly at the boil and the precipitated embonic acid removed by filtering hot
and washing twice with hot water (1 liter). The filtrate and washings were
evaporated to dryness in a steam pan and the residue recrystallized from
ethyl alcohol (1,200 ml), to yield the dibromide (320 g).
Therapeutic Function
Antihypertensive
Biochem/physiol Actions
Hexamethonium bromide is a nicotinic acetylcholine receptor (nAChR) antagonist. It preferentially blocks nicotinic receptors at autonomic ganglia. It can cross the blood-brain barrier only at high doses.
Check Digit Verification of cas no
The CAS Registry Mumber 55-97-0 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 5 and 5 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 55-97:
(4*5)+(3*5)+(2*9)+(1*7)=60
60 % 10 = 0
So 55-97-0 is a valid CAS Registry Number.

Solid-state synthesis of mixed trihalides via reversible absorption of dihalogens by non porous onium salts

1,6-Bis(trimethylammonium)hexane bis(trihalides) and mixed bis(trihalides) have been synthesized by treating the corresponding dihydrated halides with molecular dihalogens under gas-solid and solution conditions. Despite the starting halides being non-porous, the trihalide syntheses occur homogeneously, in quantitative yields, and reversibly. In all cases halogen bond prevails over hydrogen bond, dihalogens substitute for the hydration water of starting halide anions and trihalides are formed. The stability of the obtained trihalides is mainly due to cooperative halogen bond and cation templation effect. Hexamethonium halides are proven effective solids for the clathration and storage of molecular dihalogens. While the starting salts are not isostructural, all the formed trihalides and mixed trihalides are isostructural.
