In the realm of fine chemicals, understanding the specific properties and applications of each compound is crucial for successful product development and manufacturing. 2,4-Dimethylthiophenol, known scientifically by its CAS number 13616-82-5, is a prime example of such a compound. This thiophenol derivative offers a unique set of chemical characteristics that lend themselves to significant industrial uses, particularly as a chemical intermediate and a processing aid in the rubber industry. For procurement specialists and research scientists, a clear understanding of this chemical's profile and how to source it is essential.

Delving into the Chemical Profile of 2,4-Dimethylthiophenol

2,4-Dimethylthiophenol (C8H10S, MW: 138.23) presents as a clear to light yellow liquid. Its physical properties are notable: an estimated melting point of -30°C means it remains liquid under standard conditions, while its boiling point of 207-208 °C allows for distillation and purification. The density is 1.022 g/mL at 25°C, and its refractive index is 1.569. Chemically, the compound is characterized by its thiol group (-SH), which is reactive and can participate in various chemical transformations. However, it is also known for its characteristic stench, a common trait among low-molecular-weight thiols, and it is classified as flammable. Safety data sheets (SDS) highlight its potential hazards, including flammability (Fp 137 °F), and irritant properties (H315, H319, H335), underscoring the need for proper safety precautions during handling and storage.

Key Industrial Applications Revealed

The industrial significance of 2,4-Dimethylthiophenol is twofold:

  • Chemical Intermediate: As a versatile organic building block, it is employed in the synthesis of a wide array of complex organic molecules. This includes its use in the development of pharmaceuticals, agrochemicals, and other specialty chemicals where the introduction of a substituted phenylthio group or the reactivity of the thiol is beneficial.
  • Peptizer for Rubber: In the polymer industry, 2,4-Dimethylthiophenol acts as an effective peptizer. This means it helps to break down the long polymer chains in natural rubber and SBR during processing, thereby reducing the compound's viscosity. This facilitation of processing translates into easier mixing, molding, and extrusion, contributing to improved manufacturing efficiency and potentially better final product properties.

This dual functionality makes it a valuable commodity for manufacturers across different sectors.

Finding Reliable Suppliers and Manufacturers

For businesses requiring 2,4-Dimethylthiophenol, securing a consistent and high-quality supply is paramount. Global sourcing often leads to China, where a vast number of chemical manufacturers operate. When looking to purchase this compound, it is advisable to partner with reputable suppliers. Key information to seek includes the CAS number (13616-82-5), specified purity levels, and production capacity. Engaging with manufacturers who can provide technical data sheets and ensure compliance with international shipping regulations is crucial. Companies like NINGBO INNO PHARMCHEM CO.,LTD. are positioned as experienced providers, facilitating direct purchase options and ensuring product availability for their B2B clients. Requesting a quotation for bulk quantities can provide significant cost advantages.

The Advantage of Direct Procurement

Opting to buy directly from a manufacturer offers several benefits. It can lead to more competitive pricing, enhanced communication regarding product specifications and lead times, and a clearer understanding of the supply chain. For critical chemical intermediates, establishing a direct relationship with a manufacturer ensures that quality control measures are robust and that any technical queries can be addressed promptly. This direct engagement is invaluable for ensuring the smooth operation of R&D and production lines.

In essence, 2,4-Dimethylthiophenol (CAS 13616-82-5) is a chemical with important industrial applications, from acting as a key intermediate in synthesis to enhancing rubber processing. By understanding its chemical properties and working with established manufacturers and suppliers, businesses can ensure a reliable and cost-effective procurement strategy.
