Tetralithium;3-amino-5-oxido-7-sulfo-6-[[7-sulfonato-4-[(5-sulfonatonaphthalen-2-yl)diazenyl]naphthalen-1-yl]diazenyl]naphthalene-2-sulfonate

Tetralithium;3-amino-5-oxido-7-sulfo-6-[[7-sulfonato-4-[(5-sulfonatonaphthalen-2-yl)diazenyl]naphthalen-1-yl]diazenyl]naphthalene-2-sulfonate is a complex organic compound with CAS number 107246-80-0. This lithium salt contains multiple azo linkages and sulfonate groups, giving it a molecular formula of C30H17Li4N5O13S4 and a molecular weight of 811.6 g/mol. The compound belongs to the class of azo dyes and is characterized by its complex naphthalene-based structure with multiple functional groups including amino, sulfo, and diazenyl moieties.

This compound is typically a solid at room temperature with a molecular weight of 811.6 g/mol. As a lithium salt of an azo dye, it likely exhibits good water solubility due to its multiple sulfonate groups and ionic nature. The presence of conjugated azo bonds and naphthalene rings suggests it has strong chromophoric properties, meaning it absorbs visible light and displays color. The compound contains multiple polar functional groups including sulfonates and amino groups, contributing to its hydrophilic character and stability in aqueous solutions.

This compound is primarily used as an industrial dye in various applications. Its complex azo structure and multiple sulfonate groups make it suitable for textile dyeing, particularly for fabrics requiring strong, vibrant colors with good water fastness. It may also find applications in analytical chemistry as a colorimetric reagent, in the production of colored papers, inks, or coatings. The lithium salt form enhances its solubility and stability, making it particularly useful in aqueous dyeing processes and industrial applications requiring consistent color performance.

Safe handling requires standard personal protective equipment including safety glasses, chemical-resistant gloves, and laboratory clothing. While this compound does not require specific GHS hazard pictograms for human health, proper ventilation should be maintained to avoid dust inhalation. Work in well-ventilated areas and avoid generating airborne particles. Wash hands thoroughly after handling and avoid contact with eyes and skin. Although classified as Aquatic Chronic 2, it poses minimal immediate health risks when handled with standard chemical safety protocols and appropriate PPE.

This compound should be stored in a cool, dry place away from direct sunlight and heat sources to prevent degradation of the azo bonds. Keep containers tightly closed to prevent moisture absorption and contamination. Store in original packaging or suitable chemical-resistant containers with proper labeling. Avoid storage near strong oxidizing agents or acids that could potentially react with the compound. Due to its Aquatic Chronic 2 classification, ensure storage areas have appropriate containment measures to prevent environmental release in case of spills.

In case of skin contact, immediately wash the affected area with plenty of soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for at least 15 minutes and seek medical attention if irritation persists. If inhaled, move to fresh air immediately. In case of accidental ingestion, rinse mouth with water and seek medical advice. Remove contaminated clothing and wash before reuse. While this compound has no specific acute hazard classification, standard first aid measures should always be applied promptly.

Disposal must comply with local and national environmental regulations due to its Aquatic Chronic 2 classification. This compound should not be discharged directly into waterways, soil, or sewage systems. Collect waste in appropriate containers and dispose of through licensed hazardous waste disposal companies. Incineration at authorized facilities may be suitable for this organic compound. Small laboratory quantities may be treated according to institutional waste management protocols. Always consult local environmental authorities and waste management regulations before disposal to ensure compliance with current environmental protection standards.

This compound is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III, indicating it presents relatively low transport risk. Packaging must comply with UN specifications for Class 9 materials. Use appropriate cushioning and leak-proof containers to prevent spillage during transport. Shipping documents must include proper shipping name, UN number, and hazard class. Vehicles must carry appropriate placards and emergency response information. Due to its environmental hazard classification (GHS09), special care should be taken to prevent release during transport, and drivers should be aware of environmental protection measures.

This compound is not classified as a Substance of Very High Concern (SVHC) under REACH regulation. It falls under standard REACH registration requirements if manufactured or imported above threshold quantities. Under CLP regulation, it must be classified as Aquatic Chronic 2 and labeled with the GHS09 environmental pictogram. Transportation is regulated under ADR as Class 9, Group III. Companies handling this substance must comply with standard chemical safety protocols, maintain safety data sheets, and follow environmental protection measures due to its aquatic toxicity classification.
