Description

2-Mercaptoethanol CAS NO 60-24-2 is a versatile organosulfur compound characterized by its thiol and alcohol functional groups. This dual functionality makes it a critical reducing agent and a key building block in organic synthesis and biochemical applications. It is essential for industries requiring precise control over disulfide bond chemistry, protein structure analysis, and polymer modification.

Application

• Biochemistry & Molecular Biology: As a reducing agent to cleave disulfide bonds in proteins for electrophoresis (e.g., SDS-PAGE) and to maintain sulfhydryl groups in an active, reduced state.
• Pharmaceutical Synthesis: As an intermediate and protecting group reagent in the synthesis of various active pharmaceutical ingredients (APIs) and fine chemicals.
• Polymer Industry: As a chain transfer agent, cross-linking agent, or modifier in the production of specialty polymers, synthetic rubbers, and adhesives.
• Chemical Synthesis: As a nucleophile and reducing agent in organic reactions, including the synthesis of heterocycles and other sulfur-containing compounds.
• Analytical Chemistry: Used in derivatization processes for analytical detection and in buffer systems for chromatography.
• Electroplating Solutions: As an additive in certain electroplating baths to improve deposit quality and brightness.

Quality Control

Our 2-Mercaptoethanol is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, purity, and impurity profile analysis via GC, HPLC, and titration methods, to ensure it meets exacting standards for research and industrial use. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong oxidizing agents. Due to its properties of being highly volatile and easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Recommended storage temperature: 2-8°C.
