2-Picolylamine CAS 3731-51-9

1. 2-Picolylamine is a versatile building block primarily used as a ligand in coordination chemistry for synthesizing metal complexes with applications in catalysis, molecular recognition, and materials science .
2. 2-Picolylamine CAS 3731-51-9 serves as a key intermediate in pharmaceutical research for the preparation of bioactive molecules, including enzyme inhibitors, antihypertensive agents, and antimalarial drugs .
3. 2-Picolylamine is employed in the synthesis of functional materials, such as fluorescent probes and sensors, where its pyridine ring enables metal ion chelation and pH-sensitive properties .
4. In agrochemical development, 2-picolylamine is used as a precursor for herbicides, fungicides, and plant growth regulators .

1. 2-Picolylamine must be stored in a tightly sealed container under inert atmosphere (nitrogen or argon) in a cool, dry, and well-ventilated environment, protected from light and moisture .
2. 2-Picolylamine CAS 3731-51-9 is classified as a flammable liquid with GHS hazard statements H226 (Flammable liquid and vapor), H302 (Harmful if swallowed), H312 (Harmful in contact with skin), H314 (Causes severe skin burns and eye damage), and H332 (Harmful if inhaled), with signal word "Danger" .
3. Personnel must wear chemical-resistant gloves, tightly fitting safety goggles with side-shields, face protection, and flame-retardant antistatic protective clothing when handling this substance .
4. Keep 2-Picolylamine CAS 3731-51-9 away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents, strong acids, and strong bases; use explosion-proof equipment and non-sparking tools .

1. Isolate the spill area immediately, ensure adequate ventilation, remove all sources of ignition, and wear full personal protective equipment including self-contained breathing apparatus when 2-Picolylamine is released .
2. Collect 2-Picolylamine CAS 3731-51-9 using non-sparking tools by absorbing with inert materials such as sand, diatomite, or universal binders, and place into suitable closed containers for disposal .
3. Avoid creating vapors or mists during cleanup to prevent respiratory exposure; prevent 2-picolylamine from entering drains or water courses .
4. Dispose of collected material as hazardous waste according to local, state, and federal environmental regulations; note UN2735 classification (AMINES, LIQUID, CORROSIVE, N.O.S.) with packing group II .

1. 2-Picolylamine is a flammable liquid with a flash point of 86°C (closed cup) and may decompose under fire conditions, emitting toxic fumes including carbon monoxide, carbon dioxide, and nitrogen oxides (NOx) .
2. Use dry chemical powder, carbon dioxide, alcohol-resistant foam, or water spray to extinguish fires involving the product; do NOT use a direct water jet as 2-Picolylamine CAS 3731-51-9 may scatter burning material .
3. Firefighters should wear self-contained breathing apparatus in pressure-demand, MSHA/NIOSH approved, and full protective gear when handling burning 2-Picolylamine due to hazardous decomposition gases generated by thermal decomposition .
4. During combustion, may emit irritant and toxic fumes; contain fire runoff to prevent environmental contamination .
