For chemical procurement managers, R&D scientists, and formulation chemists, a deep understanding of product specifications is non-negotiable. The performance and reliability of a chemical compound often hinge on its purity, physical properties, and chemical characteristics. 5-Methyl-1H-benzotriazole (CAS 136-85-6) is no exception. As a premier supplier and manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. prides itself on providing detailed technical information to empower our B2B clients.

Unpacking the Technical Profile of 5-Methyl-1H-benzotriazole

Understanding the technical specifications of 5-Methyl-1H-benzotriazole allows industry professionals to precisely integrate it into their processes and formulations. Its chemical identity and physical attributes are key to its efficacy as a corrosion inhibitor, UV stabilizer, and synthetic intermediate.

Key Technical Specifications:

  • Chemical Name: 5-Methyl-1H-benzotriazole
  • CAS Number: 136-85-6
  • Molecular Formula: C7H7N3
  • Molecular Weight: 133.15 g/mol
  • Appearance: Typically described as a cream to beige crystalline powder or solid. High-purity grades often appear as white to off-white powder.
  • Purity: Reputable manufacturers, including ourselves, offer grades with a purity of ≥98% or ≥99%. For critical applications in pharmaceuticals or advanced materials, higher purities are often preferred.
  • Melting Point: Generally reported in the range of 78-85 °C. This property is crucial for handling, storage, and processing considerations.
  • Boiling Point: Around 323 °C at standard pressure, with decomposition potentially occurring at higher temperatures.
  • Solubility: Soluble in polar solvents like water (around 6.0 g/L at 25 °C) and alcohols, with varying degrees of solubility in other organic solvents. This impacts formulation flexibility.
  • pKa: Approximately 8.74 ± 0.40 (predicted), indicating its behavior in acidic or basic environments.
  • Stability: While generally stable, it may be sensitive to heat and light, requiring appropriate storage conditions.

The Manufacturer's Advantage: Quality Assurance

As a dedicated manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. ensures that each batch of 5-Methyl-1H-benzotriazole adheres to strict quality control measures. Our commitment to providing products with a purity of ≥99% means our clients can rely on consistent performance, whether it's for preventing metal corrosion in lubricants, enhancing UV resistance in polymers, or serving as a building block in complex organic synthesis.

Why Purity Matters for Buyers

Impurities in chemical intermediates can lead to:

  • Reduced efficacy in the final application.
  • Unwanted side reactions during synthesis.
  • Altered physical properties of formulations.
  • Compliance issues, especially in regulated industries like pharmaceuticals.

Therefore, when you buy 5-Methyl-1H-benzotriazole, prioritizing a supplier that guarantees high purity is essential for your project's success.
