N- [3- (dimethylamino) propyl] - N '-ethylcarbodiimide-iodomethane (1:1), when hiding, be sure to pay attention to many matters. This compound is very active and sensitive to temperature and humidity. Therefore, the temperature of the hiding place should be stable, and it should be controlled between 2 and 8 degrees Celsius. Do not make it warm to prevent it from decomposing and deteriorating. And it must be placed in a dry place to avoid moisture intrusion to prevent moisture decomposition or chemical reaction.
And it has certain toxicity and irritation. When storing, it should be kept away from food, medicine and humans and animals, and placed in a place beyond the reach of children. The storage device should be well sealed to prevent it from evaporating and escaping, polluting the environment, and preventing harmful gas from escaping and endangering the people around it.
Furthermore, this compound may not be stable under light, so it should be hidden in a dark place. It can be placed in a brown bottle or hidden in a dark place. Daily inspection is also essential to ensure that its packaging is intact and its properties are the same. If there is any abnormality, dispose of it quickly to ensure its quality and safety, so as to avoid accidental changes during use.

The preparation of N - [3- (dimethylamino) propyl] -N '-ethylcarbodiimide-iodomethane (1:1) is an important task in the field of organic synthesis. To obtain this compound, the following steps are often followed.
First, select a suitable starting material. Usually 3 - (dimethylamino) propylamine and N-ethylcarbodiimide are used as binders. These two play a key role in the stage of chemical reactions.
Second, choose a suitable reaction solvent. Organic solvents such as dichloromethane, N, N-dimethylformamide can provide a suitable environment for the reaction, so that the reactants can freely shuttle and interact.
Then, iodomethane is slowly added to the above mixed system. This process needs to be done with caution. Due to the active nature of iodomethane, the speed and temperature need to be precisely controlled when adding. The temperature is generally maintained between low temperature and room temperature to prevent the reaction from being too violent and causing unnecessary side reactions.
During the reaction process, the degree of reaction needs to be closely monitored. The consumption of reactants and the generation of products can be observed by analytical methods such as thin layer chromatography (TLC). When the reaction reaches the expected level, measures should be taken to stop the reaction.
After the reaction is completed, the separation and purification of the product is also crucial. The target product is often separated from the reaction mixture by column chromatography with eluents of different polarities to obtain pure N- [3- (dimethylamino) propyl] -N '-ethylcarbodiimide-iodomethane (1:1). This series of steps, which are interconnected, is the key to the synthesis of this compound.

N - [3- (dimethylamino) propyl] - N '-ethylcarbodiimide-iodomethane (1:1) is a chemical reagent. When using it, many safety precautions must be paid attention to.
First, protective measures should be comprehensive. This reagent may be irritating and may cause damage to the skin, eyes and respiratory tract. When operating, be sure to wear laboratory clothes, protective gloves and goggles to prevent the reagent from contacting the skin and eyes. If conditions permit, it is best to operate in a fume hood to prevent inhalation of volatile gaseous substances and damage to the respiratory tract.
Second, storage requirements should be followed. It should be stored in a dry, cool and well-ventilated place, away from fire and heat sources, because it is hot or exposed to open flames, or dangerous. At the same time, it should be stored separately from oxidants, acids and other substances to avoid reactions.
Third, the operating specifications should be strictly observed. When taking the reagent, the action should be cautious to avoid spilling. If it is accidentally spilled, it should be cleaned up in a timely manner according to the correct method. After use, properly dispose of the remaining reagents and waste, and do not discard them at will to prevent pollution of the environment.
Fourth, emergency treatment instructions should be known. If the skin comes into contact with this reagent, it should be immediately rinsed with a large amount of flowing water; if the eyes come into contact, it should be quickly rinsed with a large amount of water and seek medical attention in time. If inadvertently inhaled, it should be moved to fresh air as soon as possible, keep the respiratory tract unobstructed, and if necessary, perform artificial respiration and send to the hospital.
