Description

2-Aminoethyl Hydrogen Sulfate is an important organic sulfate ester and a versatile chemical intermediate. Its bifunctional nature, featuring both an amino group and a sulfate ester, makes it a valuable building block for the synthesis of surfactants, pharmaceuticals, and specialty polymers. This compound is particularly sought after by manufacturers in the chemical, pharmaceutical, and personal care industries for creating betaine-type surfactants, active pharmaceutical ingredients (APIs), and functional monomers.

Application

• Surfactant Synthesis: A key precursor for producing taurine-derived amphoteric surfactants (e.g., cocamidopropyl hydroxysultaine) used in mild shampoos, body washes, and other personal care formulations.
• Pharmaceutical Intermediates: Serves as a crucial building block in the synthesis of various active pharmaceutical ingredients (APIs) and drug candidates, particularly those requiring a sulfonated or taurine-like moiety.
• Chemical Intermediate: Used in organic synthesis for introducing the 2-aminoethylsulfate group into larger molecules, enabling the creation of specialty chemicals and functional materials.
• Polymer Modification: Employed in the production of functional polymers and resins, where it can impart cationic or zwitterionic characteristics to enhance properties like dyeability or antistatic performance.
• Biochemical Research: Utilized in laboratory settings as a reagent for studying biochemical pathways and enzyme interactions involving sulfate esters.

Quality Control

Our 2-Aminoethyl Hydrogen Sulfate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. We provide Certificates of Analysis (COA) with every shipment, detailing key parameters such as assay, water content, and related substances. Our quality commitment supports applications requiring high-purity intermediates for pharmaceutical and specialty chemical synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Recommended storage temperature is between 15°C and 25°C.
