Description

Pentadecane-1-Sulphonic Acid is a high-purity, long-chain alkyl sulfonic acid derivative, serving as a critical intermediate and functional additive in advanced chemical synthesis. Its value lies in its unique combination of a hydrophobic carbon chain and a strongly acidic sulfonic acid group, enabling its use as a surfactant, catalyst, and building block for specialty chemicals. This product is essential for manufacturers and R&D facilities in the pharmaceutical, agrochemical, and specialty surfactant industries seeking reliable, high-quality raw materials.

Application

• Surfactant & Detergent Intermediate: Acts as a key precursor for the synthesis of anionic surfactants with specific foaming and wetting properties.
• Phase-Transfer Catalyst: Utilized in organic synthesis to facilitate reactions between reagents in immiscible phases.
• Acid Catalyst: Employed in esterification, alkylation, and other acid-catalyzed reactions in fine chemical production.
• Pharmaceutical Intermediate: Serves as a building block for active pharmaceutical ingredients (APIs) and drug delivery system components.
• Agrochemical Synthesis: Used in the manufacture of herbicides, pesticides, and plant growth regulators.
• Corrosion Inhibitor Formulation: Incorporated into formulations for metal treatment and protection due to its surface-active properties.
• Research & Development: A valuable reagent for academic and industrial research in organic and polymer chemistry.
• Polymer Modification: Used to introduce sulfonic acid groups into polymers for ion-exchange membranes or enhanced hydrophilicity.

Quality Control

Our Pentadecane-1-Sulphonic Acid is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) detailing the results for all critical parameters are provided with every shipment. We are committed to supplying material that meets the stringent requirements of industrial and research applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong acid/organic solvent; containers must be kept tightly sealed to exclude moisture and stored separately from bases, oxidizers, and reactive metals.
