Benzyl (3S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylate;4-methylbenzenesulfonic acid

Benzyl (3S)-1,2,3,4-tetrahydroisoquinoline-3-carboxylate;4-methylbenzenesulfonic acid is a chemical compound with CAS number 77497-97-3 and molecular formula C24H25NO5S. This substance has a molecular weight of 439.5 g/mol and appears to be a complex organic compound combining a tetrahydroisoquinoline derivative with a tosylate salt. It is classified as hazardous to the aquatic environment with chronic toxicity category 2.

This compound is a solid organic substance with a molecular weight of 439.5 g/mol and formula C24H25NO5S. As a tosylate salt derivative, it typically exhibits good stability and moderate solubility in polar solvents. The specific physical properties such as melting point, color, and exact solubility data would depend on the manufacturing specifications and purity grade of the particular batch.

This compound is primarily used as an intermediate in pharmaceutical synthesis and organic chemistry research. Its tetrahydroisoquinoline structure makes it valuable for developing pharmaceuticals, particularly those targeting neurological conditions. The tosylate salt form enhances its stability and handling properties, making it suitable for commercial-scale synthesis processes and as a building block in medicinal chemistry applications.

Handle this substance with standard laboratory safety precautions including wearing protective gloves, safety glasses, and appropriate clothing. Work in a well-ventilated area or under a fume hood to minimize exposure. Although it has no signal word assigned, its Aquatic Chronic 2 classification requires careful handling to prevent environmental release. Avoid generating dust and ensure proper containment during transfer and weighing operations.

Store this compound in a cool, dry place away from direct sunlight and moisture. Keep containers tightly closed and properly labeled in a designated chemical storage area. As it's classified as ADR Class 9 (miscellaneous dangerous goods), ensure storage complies with local regulations for hazardous materials. Separate from incompatible materials and maintain appropriate temperature control to preserve product stability and quality.

In case of skin contact, immediately wash the affected area with plenty of soap and water. If eye contact occurs, rinse thoroughly with water for at least 15 minutes and seek medical attention. For inhalation, move to fresh air immediately. If ingested, do not induce vomiting and seek immediate medical attention. Always consult the safety data sheet for complete first aid instructions and contact emergency services if severe symptoms develop.

Dispose of this substance through licensed hazardous waste disposal facilities in accordance with local, national, and EU regulations. Due to its Aquatic Chronic 2 classification, prevent environmental release during disposal. Contact authorized waste management companies experienced in handling pharmaceutical intermediates and organic chemicals. Never dispose of through regular waste streams or pour down drains, as this could harm aquatic ecosystems.

This substance is classified as ADR Class 9 (miscellaneous dangerous goods), Packing Group III for transport purposes. Use appropriate packaging that meets UN specifications for Class 9 materials. Ensure proper labeling with GHS09 environmental hazard pictogram and required transport documentation. Follow ADR regulations for loading, segregation, and vehicle requirements when shipping within Europe, and coordinate with carriers experienced in hazardous materials transport.

This substance is subject to CLP regulation due to its Aquatic Chronic 2 classification and must display the GHS09 environmental hazard pictogram. It falls under REACH regulation for chemical registration and safety assessment within the EU. While not identified as a SVHC (Substance of Very High Concern), users must comply with standard chemical safety requirements, workplace exposure limits, and environmental protection measures for aquatic toxicity.
