Application:
5-Bromoacetyl-2-Hydroxybenzaldehyde (CAS: 115787-50-3) is the main intermediate in the preparation of Salmeterol (S090100). Salmeterol is an asthma remedy. It is developed from the molecular structure of salbutamol with only an additional tail part. This part is closely associated with the specific structure of the beta 2 receptor, the external receptor site. This allows the other parts of the molecule to act freely on the beta 2 receptor. And for this reason, this product can continue to stay in the position of action. Salmeterol can be used as a bronchodilator for long-acting beta 2 receptor agonists in daily control of asthma symptoms. It can be used for long-term treatment of asthma (including nocturnal asthma and exercise-induced asthma), reversible airway obstruction in chronic bronchitis and emphysema, and is not suitable for acute attack of asthma.
