For procurement specialists and chemical engineers in industrial settings, understanding the fundamental chemical and physical properties of raw materials is critical for effective application and safe handling. 1,3-Dimethyl-1H-pyrazol-5-amine (CAS 3524-32-1) is a fine chemical with specific characteristics that industrial buyers should be aware of when considering it for their manufacturing processes.

Physical Appearance and Form

1,3-Dimethyl-1H-pyrazol-5-amine is typically supplied as a crystalline powder. Its color is often described as light orange or off-white, depending on the purity and specific manufacturing batch. As a powder, its handling requires appropriate measures to prevent dust inhalation and dispersion, a standard consideration for any solid chemical raw material purchase.

Melting Point and Thermal Stability

A key physical characteristic for identification and quality assessment is its melting point, which for 1,3-Dimethyl-1H-pyrazol-5-amine is generally reported to be in the range of 65-69 °C. This relatively low melting point indicates that the compound can be sensitive to elevated temperatures. Buyers should confirm storage recommendations with their chemical supplier, but generally, keeping it at room temperature in a dark, inert atmosphere is advisable to maintain its integrity. Understanding this property is crucial for logistics and inventory management.

Hygroscopicity: A Note on Handling and Storage

A significant property of 1,3-Dimethyl-1H-pyrazol-5-amine is its hygroscopic nature. This means it readily absorbs moisture from the surrounding atmosphere. For industrial applications, especially those requiring anhydrous conditions or precise reagent concentrations, this characteristic necessitates careful handling. Suppliers recommend storing the material in tightly sealed containers, preferably under an inert atmosphere (like nitrogen or argon), to protect it from moisture ingress. When you buy this chemical, ensure appropriate drying procedures or storage conditions are planned for its use.

Purity and Supplier Information

When sourcing CAS 3524-32-1, particularly from manufacturers in China, industrial buyers should focus on purity levels (often 99% or higher) and check the supplier's ability to provide lot-specific quality data. The consistent quality of this fine chemical is essential for reproducible results in industrial synthesis. We, as a dedicated supplier, ensure our 1,3-Dimethyl-1H-pyrazol-5-amine meets these exacting standards.

By understanding these fundamental chemical properties, industrial buyers can make informed decisions when sourcing 1,3-Dimethyl-1H-pyrazol-5-amine, ensuring optimal usage and product quality in their operations.
