For 3-amidinopyridine hydrochloride, various matters should be paid attention to during storage and transportation. This compound is chemically active, and when storing, the first environment should be selected. It should be placed in a cool, dry and well-ventilated place, because it is easy to deteriorate due to humidity and high temperature. Moisture may cause it to hydrolyze, and high temperature may promote its chemical reaction and damage its quality.
Furthermore, the storage place should be kept away from fires and heat sources. Because of its flammability, it may be dangerous to encounter open flames and hot topics, causing the risk of combustion or even explosion. And it should be stored separately from oxidants, acids, etc., to avoid mixed storage. It is easy to react with various chemicals and cause accidents.
When transporting, there are also many precautions. The packaging must be tight to ensure that there is no leakage. The packaging materials selected must be able to resist vibration, collision and friction to prevent their damage. During transportation, the traffic should be stable to avoid severe bumps and sudden braking to avoid package damage and material leakage.
At the same time, the transporter should also be familiar with its characteristics and emergency treatment methods. Once a leak is detected, it can be dealt with quickly according to the plan to reduce its harm. And the transportation vehicle should be equipped with corresponding fire protection and leakage emergency treatment equipment to ensure safety. In this way, during the storage and transportation of 3-amidine pyridine hydrochloride, pay attention to various matters to ensure its safety, protect the environment and personal safety.
