1-Methyl-1H-pyrazol-5-amine(CAS: 1192-21-8)

1-Methyl-1H-pyrazol-5-amine is a crystalline solid with a molecular weight of approximately 119.13 g/mol. It is slightly soluble in water and ethanol. Chemically, it is mildly basic and can react with acids to form salts. It is stable under normal conditions but should be stored in a closed container to prevent moisture absorption.

1-Methyl-1H-pyrazol-5-amine is commonly synthesized via the reaction of 1-methylpyrazole with ammonia. The synthesis is conducted under basic conditions, and the product is obtained with good yield and selectivity. Catalysts such as sodium hydroxide are often used to facilitate the reaction.

1-Methyl-1H-pyrazol-5-amine finds applications in the pharmaceutical industry for the synthesis of certain drugs, as well as in the sensor technology sector for the development of gas sensors. It is also used in the preparation of polymers and as a precursor in semiconductor manufacturing.

When handling 1-Methyl-1H-pyrazol-5-amine, it is important to use personal protective equipment (PPE) such as gloves and goggles. Work should be performed in a well-ventilated area or fume hood. Spills should be cleaned up using appropriate absorbent materials, and the area should be thoroughly washed down. Always refer to the Safety Data Sheet (SDS) for detailed safety information and guidelines.
