The reliable supply of high-quality chemical intermediates is fundamental to innovation in industries ranging from polymers and imaging to pharmaceuticals. 3,5-Bis-tert-butylsalicylic Acid (CAS 19715-19-6) is one such critical compound, valued for its unique properties and diverse applications. As a dedicated manufacturer and supplier, our focus is on mastering its synthesis and implementing rigorous quality control to meet the exacting standards of our clients.

Mastering the Synthesis of 3,5-Bis-tert-butylsalicylic Acid

The production of 3,5-Bis-tert-butylsalicylic Acid involves sophisticated chemical processes. Several synthesis routes are documented, each with its own advantages in terms of yield, purity, and scalability. Common methods include:

  • Carboxylation of 2,4-Di-tert-butylphenol: This is a highly efficient route, often employing carbon dioxide under specific catalytic conditions to achieve high yields.
  • Esterification-Hydrolysis Pathway: This method typically starts with methyl salicylate, involving tert-butylation followed by hydrolysis to yield the desired product.
  • Gas-Solid Phase Carboxylation: This approach offers an alternative, sometimes achieving high purity through controlled reaction conditions.

As a manufacturer, we continuously refine these processes to optimize efficiency, minimize environmental impact, and ensure consistent product quality. The choice of synthesis method is often dictated by the scale of production and the specific purity requirements for the end application. When you buy 3,5-Bis-tert-butylsalicylic Acid, you are benefiting from our expertise in these complex syntheses.

The Importance of Stringent Quality Control

For a compound like 3,5-Bis-tert-butylsalicylic Acid, which finds use in sensitive applications such as pharmaceutical synthesis and high-performance toners, quality control is non-negotiable. Our quality assurance processes are comprehensive and include:

  • Purity Analysis: High-Performance Liquid Chromatography (HPLC) is routinely used to determine the assay and identify any impurities, ensuring a minimum purity of 99%.
  • Physical Property Verification: Parameters such as melting point (typically 160-161°C) and appearance (white crystalline powder) are critical indicators of product quality.
  • Moisture Content: Karl Fischer titration is employed to ensure low volatile matter content, typically below 0.5%.
  • Spectroscopic Analysis: Techniques like NMR and IR spectroscopy are used for structural confirmation.

These rigorous checks guarantee that every batch of 3,5-Bis-tert-butylsalicylic Acid we supply meets the highest industry standards. Our commitment is to provide you with a reliable and high-purity chemical, enabling your research and production to proceed without compromise.
