S-Carboxymethyl-L-cysteine/ Carboxymethylcysteine/ Carbocysteine CAS 638-23-3

 

 

Description:
Carbocysteine is a mucolytic agent and expectorant that is used to help thin and loosen mucus in the respiratory tract. It is a synthetic compound derived from cysteine by replacing the thiol group (-SH) with a carboxymethyl group (-CH2COOH).

Specification:

• Chemical Formula: C5H9NO4S
• Molecular Weight: Approximately 179.19 g/mol
• Appearance: White to off-white crystalline powder
• Solubility: Soluble in water and alcohol
• Melting Point: Approximately 213-216°C
• pKa: Approximately 2.93 (acidic)

Application:

1. Respiratory Conditions: Carbocysteine is primarily used in the treatment of respiratory conditions characterized by excessive mucus production and difficulty in expectoration. It helps to break down and liquefy mucus, making it easier to cough up. It is commonly used in conditions such as bronchitis, chronic obstructive pulmonary disease (COPD), and other respiratory tract infections.
2. Cystic Fibrosis: Carbocysteine may be prescribed for individuals with cystic fibrosis, a genetic disorder that affects the lungs and other organs, leading to the accumulation of thick mucus. It can help improve mucus clearance and reduce symptoms.
3. Sinusitis: In some cases, carbocysteine may be used to aid in the management of sinusitis, a condition characterized by inflammation and congestion of the sinuses. It helps to promote drainage and alleviate nasal congestion.
4. Other Mucolytic Uses: Carbocysteine can also be employed to facilitate the removal of thick mucus in postoperative conditions, during bronchoscopy, or in situations where mucus clearance is impaired.

Features:

1. Mucolytic Action: Carbocysteine acts as a mucolytic agent by breaking down disulfide bonds in mucus glycoproteins, reducing the viscosity of mucus and facilitating its removal.
2. Expectorant Properties: It helps to promote expectoration by thinning and loosening mucus, making it easier to cough up and clear the airways.
3. Anti-inflammatory Effects: Carbocysteine possesses mild anti-inflammatory properties, which may help reduce inflammation in the respiratory tract and alleviate associated symptoms.
4. Generally Well-Tolerated: Carbocysteine is usually well-tolerated, with the most common side effects being mild gastrointestinal symptoms such as nausea, diarrhea, and stomach discomfort.
5. Oral Administration: It is commonly available in oral dosage forms, such as tablets, capsules, or syrups, for convenient administration.
