Levodropropizine CAS 99291-25-5

1. Levodropropizine is primarily used as a peripheral antitussive (non-opioid) medication for the symptomatic treatment of dry or persistent cough caused by respiratory conditions such as upper respiratory tract infections, pharyngitis, bronchitis, and asthma .
2. Levodropropizine CAS 99291-25-5 is also employed in biochemical and pharmacological research as a histamine receptor inhibitor, where it reduces cough by interfering with sensory neuropeptide activation in peripheral C-fibers .
3. Levodropropizine serves as a key reference standard in pharmaceutical testing, particularly as European Pharmacopoeia (EP) and USP reference material for quality control and impurity analysis .
4. Researchers utilize Levodropropizine CAS 99291-25-5 to study non-opioid antitussive mechanisms with reduced central nervous system side effects compared to traditional opioids like codeine .

1. Levodropropizine must be stored in a tightly sealed container in a cool, dry, and well-ventilated environment, protected from light and heat, with recommended storage at 2-8°C for pharmaceutical standards or -20°C for long-term stability of stock solutions .
2. Levodropropizine CAS 99291-25-5 is classified as a pharmaceutically active ingredient requiring handling only by trained personnel, with hazard statements including R28 (very toxic if swallowed), R38 (irritating to skin), and R41 (risk of serious damage to eyes) .
3. Personnel must wear chemical-resistant rubber gloves, chemical safety goggles, and protective clothing when handling Levodropropizine, avoiding inhalation of dust and contact with skin, eyes, and clothing .
4. Follow safety statements S24/25 (avoid contact with skin and eyes), S26 (rinse immediately with water if in eyes), and S36/37/39 (wear protective clothing, gloves, and eye/face protection) when working with this substance .

1. Isolate the spill area, ensure adequate ventilation, and wear full personal protective equipment including NIOSH/MSHA-approved respirator when Levodropropizine is released, avoiding dust formation .
2. Collect Levodropropizine CAS 99291-25-5 by sweeping or vacuuming without creating dust, using spark-proof tools, and place into suitable closed containers for disposal according to local regulations .
3. Avoid creating dust clouds during cleanup to prevent respiratory exposure, and prevent the product from entering drains or water courses due to potential environmental hazards .
4. Dispose of collected material in accordance with prevailing country, federal, state, and local environmental regulations, as this substance is considered non-hazardous for transport but contains a potent active ingredient .

1. Levodropropizine is not classified as highly flammable but may decompose under fire conditions, with a flash point of approximately 140°C (284°F) and may emit toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides .
2. Use Levodropropizine CAS 99291-25-5 water spray, carbon dioxide, dry chemical powder, or alcohol-resistant foam to extinguish fires involving the product .
3. Firefighters should wear self-contained breathing apparatus and full protective clothing when handling burning Levodropropizine due to hazardous decomposition gases and to prevent contact with skin and eyes .
4. During combustion, may Levodropropizine CAS 99291-25-5 emit irritant and toxic fumes; move containers from the fire area if safe to do so, cool exposed containers with water spray, and contain fire runoff to prevent environmental contamination .
