2-[4-[5-(4-chlorophenyl)-3,4-dihydropyrazol-2-yl]phenyl]sulfonyl-N,N-dimethylethanamine;formic acid

2-[4-[5-(4-chlorophenyl)-3,4-dihydropyrazol-2-yl]phenyl]sulfonyl-N,N-dimethylethanamine;formic acid is an organic chemical compound with CAS number 133514-97-3 and molecular formula C20H24ClN3O4S. This substance has a molecular weight of 437.9 g/mol and contains a pyrazoline ring system with chlorophenyl and sulfonyl functional groups. It is classified as a hazardous substance requiring careful handling due to its corrosive and sensitizing properties.

This compound is a complex organic molecule with a molecular weight of 437.9 g/mol and formula C20H24ClN3O4S. The presence of formic acid as a salt former suggests it exists as a formate salt, which typically enhances water solubility compared to the free base. The compound contains polar sulfonyl and amine groups alongside aromatic chlorophenyl moieties, influencing its solubility profile and chemical reactivity.

This compound is primarily used as an intermediate in pharmaceutical synthesis and chemical research applications. The pyrazoline structure with chlorophenyl and sulfonyl groups suggests potential use in developing bioactive compounds or pharmaceutical ingredients. Its specific molecular architecture makes it valuable for medicinal chemistry research and as a building block in organic synthesis processes requiring specialized heterocyclic intermediates.

Safe handling requires full personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Skin Corr. 1B classification. Work in well-ventilated areas or fume hoods to prevent inhalation exposure, as it may cause respiratory sensitization. Avoid direct skin contact as the substance can cause severe burns and allergic reactions. Always have emergency shower and eyewash stations readily accessible when handling this material.

Store this compound in a cool, dry, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Use corrosion-resistant containers with tight-fitting lids due to its corrosive nature. Keep containers properly labeled and segregated from other chemicals. Storage areas should have appropriate containment measures and be accessible only to trained personnel wearing proper protective equipment.

Immediate action is required due to the substance's corrosive properties. For skin contact, immediately flush with large amounts of water for at least 15 minutes while removing contaminated clothing. For eye contact, rinse thoroughly with water and seek immediate medical attention. If inhaled, move to fresh air and seek medical help if respiratory symptoms develop. Always consult a physician after any significant exposure incident.

Disposal must comply with local and national hazardous waste regulations due to its corrosive and environmentally hazardous classification (Aquatic Acute 1, Aquatic Chronic 1). Contact licensed hazardous waste disposal companies for proper treatment and disposal. Never discharge to sewers or waterways as it poses significant environmental risks. Small quantities may require neutralization before disposal, but this should only be performed by trained professionals following appropriate protocols.

This substance is classified as ADR Class 8 (corrosive substances), Packing Group II, requiring specialized packaging and transport procedures. Use appropriate corrosion-resistant packaging that meets UN specification requirements for Class 8 materials. Transport vehicles must display proper hazard placards and carry emergency response information. Only qualified carriers experienced in handling corrosive chemicals should transport this material, following all applicable dangerous goods regulations.

This substance is subject to CLP regulation classification requirements and must be labeled with GHS pictograms GHS05, GHS07, GHS08, and GHS09. It requires safety data sheets under REACH regulation for professional users. The compound is not currently listed as a SVHC (Substance of Very High Concern), but its multiple hazard classifications require compliance with occupational health and environmental protection regulations across European jurisdictions.
