Description

Guaiacol is a naturally occurring organic compound and a key aromatic building block with a characteristic smoky, phenolic odor. It serves as a fundamental intermediate in the synthesis of a wide range of high-value chemicals, including pharmaceuticals, agrochemicals, and flavor & fragrance ingredients. This versatile compound is essential for manufacturers in the pharmaceutical, food & beverage, and fine chemical industries seeking a reliable and high-purity raw material.

Application

• Pharmaceutical Synthesis: A crucial precursor in the manufacture of active pharmaceutical ingredients (APIs), such as expectorants (e.g., guaifenesin) and other therapeutic agents.
• Flavor & Fragrance Industry: Used as a starting material for synthesizing vanillin and other aroma chemicals, imparting smoky, woody, and spicy notes to food products and perfumes.
• Agrochemical Production: Serves as an intermediate in the synthesis of certain pesticides, herbicides, and plant growth regulators.
• Chemical Research & Development: Employed as a reagent and building block in organic synthesis for developing new compounds and materials.
• Antioxidant Applications: Utilized in some industrial formulations for its antioxidant properties.
• Specialty Chemical Manufacturing: Acts as an intermediate for dyes, resins, and other fine chemicals.

Quality Control

Our Guaiacol is produced under stringent quality management systems to ensure batch-to-batch consistency and high purity. We offer grades suitable for various industrial applications, with specifications meeting or exceeding standard industry requirements. Certificates of Analysis (COA) documenting key parameters such as assay, identity, and impurity profiles are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Recommended storage temperature: 15-25°C.
