3-(2-chloroethyl)-2-methyl-6,7,8,9-tetrahydropyrido[1,2-a]pyrimidin-4-one;hydrochloride

3-(2-chloroethyl)-2-methyl-6,7,8,9-tetrahydropyrido[1,2-a]pyrimidin-4-one;hydrochloride is a synthetic organic compound with the molecular formula C11H16Cl2N2O and CAS number 93076-03-0. This heterocyclic compound features a fused pyrido-pyrimidinone ring system with a chloroethyl substituent. With a molecular weight of 263.16 g/mol, it is classified as a hazardous substance requiring careful handling due to its toxicological properties and environmental impact potential.

The compound is a hydrochloride salt form of the parent molecule, typically appearing as a crystalline solid at room temperature. As a hydrochloride salt, it generally exhibits improved water solubility compared to the free base. The presence of chlorine atoms and nitrogen-containing heterocycles contributes to its chemical reactivity. Specific physical properties such as melting point, exact color, and odor characteristics should be confirmed through analytical testing or supplier documentation.

This compound is primarily used as a research chemical and pharmaceutical intermediate in laboratory settings. Its structural features make it valuable for medicinal chemistry research, particularly in drug discovery programs targeting specific biological pathways. The compound may serve as a building block for synthesizing more complex molecules or as a reference standard in analytical applications. Its use is typically restricted to professional research environments due to its hazardous classification.

Safe handling requires comprehensive personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Acute Toxicity 3, Eye Damage 1, and Skin Sensitization 1 classifications. Work must be conducted in well-ventilated areas or under fume extraction systems. Avoid skin and eye contact, inhalation, and ingestion. Use appropriate dispensing tools to minimize direct contact. Emergency wash facilities should be readily accessible, and personnel should be trained in proper handling procedures before use.

Proper storage requires a cool, dry, well-ventilated area away from direct sunlight and heat sources. The substance should be kept in tightly sealed, chemically compatible containers to prevent moisture absorption and contamination. Store separately from incompatible materials such as strong oxidizing agents and bases. Access should be restricted to authorized personnel only. Storage areas must be equipped with appropriate spill containment measures and maintained according to local chemical storage regulations.

Immediate first aid measures include removing contaminated clothing and flushing affected skin areas with copious amounts of water for at least 15 minutes. For eye contact, irrigate with clean water for at least 15 minutes while holding eyelids open. If inhaled, move the person to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical attention. Always consult a physician after any exposure incident and provide the safety data sheet to medical personnel.

Disposal must comply with local, national, and international hazardous waste regulations due to its toxic and environmentally hazardous classifications. The substance cannot be disposed of through regular waste streams and requires specialized hazardous waste treatment. Contact licensed waste disposal companies experienced in handling toxic chemical waste. Containers must be properly labeled and documented according to waste tracking requirements. Never pour down drains or release into the environment due to its Aquatic Chronic 2 classification.

Transportation is regulated under ADR Class 6.1 (Toxic substances), Packing Group III, requiring compliant packaging, labeling, and documentation. Packages must bear appropriate hazard labels including GHS06, GHS08, GHS05, and GHS09 pictograms with 'Danger' signal word. Transport vehicles must carry appropriate emergency equipment and personnel must be trained in hazardous materials handling. Shipping documentation must include proper shipping names, hazard classifications, and emergency contact information according to dangerous goods regulations.

The compound is subject to multiple European regulations including REACH registration requirements for commercial use and CLP regulation for classification, labeling, and packaging. While not currently listed as a Substance of Very High Concern (SVHC), its hazardous classification requires compliance with occupational health and safety regulations. Users must maintain safety data sheets, implement risk management measures, and report usage according to regulatory requirements. Import/export may require additional permits depending on jurisdiction and intended use.
