- CAS No.: 62-51-1
- Formula:C8H18ClNO2
- Molecular Weight:195.69
IUPAC Name: 2-acetoxy-N,N,N-trimethylpropan-1-aminium chloride
InChIKey: JHPHVAVFUYTVCL-UHFFFAOYSA-M
SMILES: CC(OC(C)=O)C[N+](C)(C)C.[Cl-]
Biological Activity: Methacholine (Acetyl-β-methylcholine) choride is a potent muscarinic-3 (M3) agonist. Methacholine choride acts directly on acetylcholine receptors on smooth muscle causing bronchoconstriction and airway narrowing. Methacholine choride shows a high sensitivity to identify bronchial hyperresponsiveness (BHR). Methacholine choride can be used to measure airway hyperresponsiveness (AHR) as a diagnostic aid in the assessment of individuals with asthma-like symptoms and normal resting expiratory flow rates[1][2][3][4].
