Description

Tridecanoic Acid CAS NO 638-53-9 is a saturated medium-chain fatty acid, also known as tridecylic acid, with a 13-carbon backbone. This high-purity chemical intermediate is valued for its defined structure and consistent quality, which are critical for precision synthesis and formulation. It serves as a key building block for researchers and manufacturers in the pharmaceutical, cosmetic, and specialty chemical industries seeking reliable raw materials for esters, lubricants, and surfactants.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its defined carbon chain length is crucial.
• Fragrance & Flavor Ingredient: Serves as a precursor for esters used in perfumery and flavoring agents due to its clean, fatty acid profile.
• Lubricant & Plasticizer Additive: Employed in the production of synthetic esters that act as base stocks for lubricants or as specialty plasticizers.
• Surfactant & Detergent Synthesis: Acts as a hydrophobic feedstock for manufacturing anionic and nonionic surfactants.
• Cosmetic Emollient: Used to create derivatives that function as skin-conditioning agents and emollients in personal care formulations.
• Research & Development: A standard compound for analytical chemistry, biochemistry research, and as a reference material in chromatography.
• Corrosion Inhibitor Precursor: Converted into derivatives that provide protective films in metalworking fluids and industrial coatings.
