3-[[4-(dimethylamino)benzoyl]amino]propyl-dodecyl-dimethylazanium;4-methylbenzenesulfonate

3-[[4-(dimethylamino)benzoyl]amino]propyl-dodecyl-dimethylazanium;4-methylbenzenesulfonate is a quaternary ammonium compound with surfactant properties, identified by CAS number 156679-41-3. This complex organic molecule has a molecular formula of C33H55N3O4S and a molecular weight of 589.9 g/mol. It contains both a quaternary ammonium cation with a long alkyl chain and a tosylate anion, giving it amphiphilic characteristics typical of surfactants and antimicrobial agents.

This quaternary ammonium compound is typically a solid at room temperature due to its ionic nature and high molecular weight of 589.9 g/mol. The presence of both hydrophilic quaternary ammonium groups and hydrophobic dodecyl chains suggests amphiphilic behavior with surface-active properties. The compound likely exhibits good solubility in polar solvents and demonstrates typical surfactant characteristics including foaming and emulsifying properties. Specific physical appearance and odor characteristics would depend on purity and formulation conditions.

This quaternary ammonium compound is primarily used as a surfactant and antimicrobial agent in various industrial applications. Its amphiphilic structure makes it suitable for formulations requiring emulsification, solubilization, or surface tension reduction. Common applications include personal care products, industrial cleaning formulations, and antimicrobial preparations. The compound's cationic nature also makes it effective as a conditioning agent in cosmetic formulations and as a biocide in water treatment applications where antimicrobial activity is required.

Safe handling requires appropriate personal protective equipment due to its Eye Dam. 1 and Skin Sens. 1 classifications. Wear chemical-resistant gloves, safety goggles with side shields, and protective clothing to prevent skin and eye contact. Ensure adequate ventilation in work areas and avoid generating dust or aerosols. The compound can cause serious eye damage and skin sensitization, so immediate washing is essential after any contact. Handle in designated areas with emergency eyewash stations readily available.

Store this compound in a cool, dry, well-ventilated area away from incompatible materials. Keep containers tightly closed and protected from moisture due to its ionic nature. Given its Aquatic Acute 1 and Aquatic Chronic 1 classifications, ensure storage areas have appropriate containment to prevent environmental release. Store away from strong oxidizing agents and acids that may react with the quaternary ammonium structure. Maintain storage temperatures below 25°C when possible to ensure product stability and prevent degradation.

Immediate action is critical due to the Eye Dam. 1 classification. For eye contact, rinse immediately with plenty of water for at least 15 minutes and seek immediate medical attention as serious eye damage can occur. For skin contact, wash thoroughly with soap and water and remove contaminated clothing. Due to Skin Sens. 1 classification, monitor for allergic reactions. If inhaled, move to fresh air immediately. In case of ingestion, rinse mouth and seek medical advice immediately without inducing vomiting.

Disposal must comply with local and national environmental regulations due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications. The compound cannot be disposed of via normal waste streams or sewage systems due to its environmental hazards. Arrange disposal through licensed hazardous waste contractors who can handle quaternary ammonium compounds appropriately. Small quantities may require neutralization or specialized treatment before disposal. Always consult local environmental authorities and follow waste classification codes for proper disposal procedures.

This compound is classified as ADR Class 9 (Miscellaneous Dangerous Goods), Packing Group III, indicating moderate transport hazard. Use appropriate UN-specification packaging suitable for Class 9 materials with proper hazard labels and documentation. Vehicles must carry appropriate emergency response information and drivers require ADR certification. Ensure packages are properly marked with UN numbers and hazard diamonds including GHS05, GHS07, and GHS09 pictograms. Follow ADR regulations for loading, segregation, and route restrictions for Class 9 dangerous goods.

This compound is subject to REACH regulation requiring registration for manufacture or import above 1 tonne annually in the EU. CLP regulation applies due to its Eye Dam. 1, Skin Sens. 1, and aquatic hazard classifications, requiring appropriate labeling with Danger signal word and GHS pictograms. It is not currently identified as a SVHC (Substance of Very High Concern). Biocide regulation may apply if used for antimicrobial purposes. Users must comply with occupational exposure limits and environmental discharge restrictions due to its aquatic toxicity.
