2-Chlorobenzaldehyde CAS 89-98-5

1. 2-Chlorobenzaldehyde is widely utilized as a key intermediate in the synthesis of various pharmaceuticals, including dihydropyrimidine derivatives, and in the production of agrochemicals and fine chemicals .
2. 2-Chlorobenzaldehyde CAS 89-98-5 serves as an important building block for manufacturing dyes, pigments, and optical brighteners, and is integral in the formulation of products for the textile and coatings industries .
3. Applications of 2-Chlorobenzaldehyde also include its use in organic synthesis as a precursor for complex molecules, such as 2-chlorodialkylbenzylamines, and in material science research for developing new polymers and resins .

1. Store 2-Chlorobenzaldehyde in a tightly sealed container under an inert atmosphere, protected from light and moisture, in a cool, dry, and well-ventilated area; recommended storage temperatures range from 2-8°C (refrigerated) to a cool, dark place .
2. Keep 2-Chlorobenzaldehyde strictly away from strong oxidizing agents, strong bases, strong reducing agents, and iron to prevent hazardous reactions, as 2-Chlorobenzaldehyde CAS 89-98-5 is moisture and light sensitive .
3. Always use appropriate personal protective equipment (PPE) including tightly fitting safety goggles, face shield, and chemical-resistant gloves (e.g., nitrile); handle 2-Chlorobenzaldehyde only in a fume hood with adequate ventilation to avoid contact with skin, eyes, and inhalation of vapors .

1. Immediately isolate the spill area (at least 50 meters/150 feet for liquids), eliminate all ignition sources, and provide adequate ventilation. Contain 2-Chlorobenzaldehyde using dry, inert, non-combustible absorbent material (e.g., dry sand) and DO NOT use water or combustible materials like cellulose-based absorbents .
2. Carefully collect 2-Chlorobenzaldehyde CAS 89-98-5 using non-sparking tools (or an electrically protected vacuum cleaner) into sealed, labeled corrosion-resistant chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear full chemical-protective equipment including self-contained breathing apparatus (SCBA) during cleanup. 2-Chlorobenzaldehyde is classified for transport (UN3265, Hazard Class 8, PG III) and requires professional hazardous waste disposal .

1. 2-Chlorobenzaldehyde is classified as a corrosive substance (GHS Category 1B, Danger) causing severe skin burns (H314) and serious eye damage (H318); 2-Chlorobenzaldehyde CAS 89-98-5 is also harmful if swallowed (LD50 oral rat: 2,160 mg/kg) and may be fatal if inhaled . Some sources classify 2-Chlorobenzaldehyde CAS 89-98-5 as a skin and eye irritant .
2. 2-Chlorobenzaldehyde is combustible with a flash point ranging from 87°C to 104°C (190°F) and an autoignition temperature of 385-395°C . It is moisture and light sensitive, reacts with strong oxidizers and bases, and when heated to decomposition, 2-Chlorobenzaldehyde CAS 89-98-5 emits toxic fumes including hydrogen chloride and carbon oxides .
3. 2-Chlorobenzaldehyde is toxic to aquatic organisms with long-lasting effects and should not be released into the environment. The NFPA health rating is 3 (serious hazard) . Always consult the specific Safety Data Sheet (SDS) for 2-Chlorobenzaldehyde CAS 89-98-5 for complete hazard information and first-aid procedures (P301+P330+P331 for ingestion, P305+P351+P338 for eyes, P303+P361+P353 for skin) .
