4-methoxybenzene-1,3-diamine

4-methoxybenzene-1,3-diamine is an aromatic organic compound with the molecular formula C7H10N2O and CAS number 615-05-4. This chemical features a benzene ring substituted with a methoxy group (-OCH3) and two amino groups (-NH2) at positions 1 and 3. With a molecular weight of 138.17 g/mol, it belongs to the class of substituted anilines and is classified as a hazardous substance requiring careful handling due to its carcinogenic and mutagenic properties.

4-methoxybenzene-1,3-diamine appears as a solid crystalline material at room temperature due to its aromatic structure and hydrogen bonding capacity from the amino groups. The presence of both hydrophilic amino groups and the methoxy substituent influences its solubility characteristics. Like most aromatic amines, it typically exhibits limited water solubility but better solubility in organic solvents. The compound may darken upon exposure to air and light due to oxidation processes common in aromatic amines.

4-methoxybenzene-1,3-diamine serves primarily as an intermediate in the synthesis of dyes, pigments, and other organic compounds in the chemical industry. Its structure with two amino groups makes it valuable for creating azo dyes and other colorants through diazotization reactions. The compound may also be used in pharmaceutical synthesis and as a building block for specialty chemicals. Due to its hazardous classification, its use is restricted to professional industrial applications with appropriate safety measures.

4-methoxybenzene-1,3-diamine requires strict safety protocols due to its carcinogenic (1B) and mutagenic (2) classification. Personnel must wear appropriate PPE including chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Skin contact must be avoided completely, and contaminated clothing should be removed immediately. Only trained professionals should handle this substance, following established occupational safety guidelines and emergency procedures.

4-methoxybenzene-1,3-diamine must be stored in tightly sealed containers in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Storage areas should be secure and accessible only to authorized personnel due to the substance's hazardous nature. The material should be kept away from incompatible substances such as strong oxidizing agents and acids. Storage facilities must comply with local regulations for carcinogenic substances, including appropriate labeling, containment measures, and emergency response equipment.

Immediate action is required upon contact with 4-methoxybenzene-1,3-diamine due to its toxic properties. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult poison control or medical professionals promptly after any exposure incident.

4-methoxybenzene-1,3-diamine disposal must comply with local and national hazardous waste regulations due to its carcinogenic classification and environmental impact (Aquatic Chronic 2). The substance cannot be disposed of in regular waste streams and requires treatment by licensed hazardous waste contractors. Disposal methods typically include high-temperature incineration at authorized facilities equipped with appropriate emission controls. All disposal activities must be documented, and waste containers must be properly labeled with hazard information before collection by certified waste management companies.

4-methoxybenzene-1,3-diamine is classified as ADR Class 9 (Miscellaneous dangerous substances), Packing Group III for transportation purposes. This classification requires specific packaging, labeling, and documentation during transport. Packages must display appropriate hazard labels including GHS pictograms (GHS07, GHS08, GHS09) and carry proper shipping documentation. Drivers must be trained in dangerous goods transport, and vehicles should carry appropriate emergency equipment. Transport must comply with ADR regulations and any additional national requirements for carcinogenic substances.

4-methoxybenzene-1,3-diamine is subject to comprehensive regulatory oversight under European chemicals legislation including REACH and CLP regulations. Its classification as Carcinogenic 1B and Mutagenic 2 places it under strict occupational exposure controls and requires specialized handling procedures. While not currently listed as an SVHC, the substance may be subject to authorization or restriction procedures. Companies must maintain safety data sheets, conduct risk assessments, and implement appropriate risk management measures. National regulations may impose additional requirements for workplace exposure limits and monitoring.

4-methoxybenzene-1,3-diamine is available through specialized chemical distributors like OYSI, which serves the European market with technical chemicals for professional and industrial applications. Due to its hazardous classification, procurement requires verification of legitimate industrial use and compliance with regulatory requirements. Buyers must demonstrate appropriate handling capabilities, storage facilities, and safety measures. OYSI can provide technical support, safety documentation, and regulatory guidance to ensure compliant procurement and use of this controlled substance by qualified industrial customers.
