Description

Isopropyl Hydrogen Sulphate is an important organic sulfate ester, widely recognized by its CAS registry number 6914-90-5. This versatile chemical intermediate is valued for its reactivity as a strong acid and its solubility in organic media, making it a key building block in specialized synthesis. It is primarily sought after by manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries for alkylation and sulfation reactions.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs via sulfation or as an alkylating agent.
• Agrochemical Synthesis: Serves as a key reagent in the production of herbicides, pesticides, and plant growth regulators.
• Surfactant & Detergent Manufacturing: Acts as a sulfating agent in the production of specialized anionic surfactants and emulsifiers.
• Polymer & Resin Modification: Employed to introduce sulfate ester groups into polymers, altering solubility and surface properties.
• Organic Synthesis Reagent: Utilized in laboratory and industrial-scale organic reactions for introducing the isopropyl sulfate moiety.
• Catalyst & Co-catalyst: Functions as a strong acid catalyst in certain esterification and condensation reactions.

Quality Control

Our Isopropyl Hydrogen Sulphate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with every shipment to guarantee it meets your specific application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed to prevent absorption of atmospheric moisture. Keep away from strong bases and incompatible materials.
