3-hydroxy-N-(2-methoxyphenyl)-2-[[4-[2-(1-methylpyridin-1-ium-2-yl)ethenyl]phenyl]diazenyl]but-2-enamide acetate

3-hydroxy-N-(2-methoxyphenyl)-2-[[4-[2-(1-methylpyridin-1-ium-2-yl)ethenyl]phenyl]diazenyl]but-2-enamide acetate is an organic chemical compound with CAS number 121315-16-0 and molecular formula C27H28N4O5. This complex molecule has a molecular weight of 488.5 g/mol and contains multiple functional groups including hydroxyl, methoxy, diazenyl, and acetate moieties. The compound is classified as a skin sensitizer and poses chronic aquatic toxicity risks, requiring careful handling in industrial applications.

The compound exhibits a molecular weight of 488.5 g/mol with the molecular formula C27H28N4O5. As an organic compound containing aromatic rings, azo linkages, and polar functional groups, it likely presents as a colored solid due to the extended conjugated system including the diazenyl group. The presence of both hydrophilic (hydroxyl, acetate) and hydrophobic (aromatic) regions suggests moderate solubility in polar solvents. Specific physical parameters like melting point and exact solubility data would require laboratory analysis.

The compound is primarily used in specialized industrial applications requiring its unique chemical structure. Given its complex aromatic system with azo linkages and pyridinium functionality, it likely serves in advanced chemical synthesis, pharmaceutical intermediates, or specialized materials applications. The specific diazenyl group suggests potential use in dye chemistry or as a chromogenic reagent. However, its skin sensitizing properties limit its use to controlled industrial environments with appropriate safety measures.

Safe handling requires strict skin contact prevention due to the compound's Skin Sens. 1 classification. Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing covering all exposed skin. Work should be conducted in well-ventilated areas or under fume extraction systems. Avoid generating dust or aerosols, and ensure emergency eyewash and shower facilities are readily accessible. All personnel must be trained on sensitization risks and proper decontamination procedures before handling this material.

The compound should be stored in tightly sealed, labeled containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Given its aquatic chronic toxicity classification, storage areas must be designed to prevent environmental release through appropriate secondary containment. Keep away from incompatible materials such as strong oxidizers and reducing agents. Storage facilities should be equipped with spill containment measures and restrict access to trained personnel only.

Immediate skin contact requires thorough washing with soap and water for at least 15 minutes while removing contaminated clothing. For eye contact, flush immediately with clean water for 15-20 minutes and seek medical attention. If inhaled, move the person to fresh air and monitor for respiratory distress. Due to the skin sensitization potential, any exposure should be documented and medical evaluation considered. Do not use solvents or harsh chemicals for decontamination as they may increase absorption.

Disposal must be conducted through licensed hazardous waste contractors due to the compound's skin sensitization and aquatic toxicity properties. The material cannot be discharged to sewers or waterways given its Aquatic Chronic 2 classification. Incineration at authorized high-temperature facilities is typically the preferred disposal method for organic compounds of this complexity. All disposal activities must comply with local and EU waste regulations, and waste manifests should properly identify the material using its CAS number 121315-16-0.

The compound is classified as ADR Class 9 (Miscellaneous Dangerous Substances), Packing Group III for transportation purposes. This requires appropriate UN-specification packaging, proper hazard labeling, and transport documentation including safety data sheets. Vehicles must carry appropriate emergency equipment and drivers need ADR training certification. The relatively low-hazard Packing Group III classification allows for standard industrial chemical transport procedures, but environmental protection measures must be in place due to aquatic toxicity concerns.

The compound is subject to EU CLP regulation requiring hazard classification as Skin Sens. 1 and Aquatic Chronic 2, with mandatory Warning signal word and GHS07/GHS09 pictograms on labels and safety data sheets. REACH registration requirements apply for manufacturers and importers above tonnage thresholds. The substance is not currently listed as SVHC (Substance of Very High Concern). Workplace exposure limits and occupational health surveillance may be required due to skin sensitization properties.
