In the world of chemical procurement and research, CAS (Chemical Abstracts Service) Registry Numbers are the universally recognized identifiers for chemical substances. For those working with advanced chemical intermediates, understanding the significance of a specific CAS number is crucial for accurate sourcing and application. Today, we focus on CAS 19721-22-3, the unique identifier for 3-Mercapto-1-propanol.

What is CAS 19721-22-3?

CAS 19721-22-3 refers to 3-Mercapto-1-propanol, a clear, colorless liquid chemical compound characterized by its dual functional groups: a thiol (-SH) and a primary alcohol (-OH). This bifunctionality makes it exceptionally useful in a variety of sophisticated applications.

Key Applications Associated with CAS 19721-22-3:

  • Surface Science: Used extensively in the preparation of hydrophilic self-assembled monolayers (SAMs) on surfaces like gold, which is vital for modifying surface properties in advanced materials and nanotechnology.
  • Organic Synthesis: Serves as a traceless linker molecule in the synthesis of complex structures, particularly in the field of oligosaccharides, where its structure facilitates controlled chain elongation and clean removal.
  • Bioconjugation: Its thiol group allows for efficient conjugation with biomolecules or surfaces, opening doors for advancements in diagnostics and targeted drug delivery systems.

Why Purity Matters for CAS 19721-22-3?

As with most specialized chemical intermediates, the performance of 3-Mercapto-1-propanol in its intended applications is highly dependent on its purity. Impurities can interfere with the delicate self-assembly processes, hinder chain elongation in synthesis, or lead to unpredictable surface characteristics. Therefore, when you buy 3-Mercapto-1-propanol, it's essential to ensure it meets rigorous quality standards, typically with an assay of 98.5% or higher.
