For professionals in chemical procurement, research and development, and product formulation, a deep understanding of chemical properties is essential for effective application. 1-Methoxy-2-propyl Acetate (PGMEA), identified by CAS 108-65-6, is a widely used industrial solvent whose specific characteristics make it valuable across diverse sectors, including electronics, coatings, and inks. As a dedicated supplier of 1-Methoxy-2-propyl Acetate, we aim to provide insights into its key properties that drive its utility.

Key Chemical and Physical Properties of PGMEA (CAS 108-65-6)

1-Methoxy-2-propyl Acetate is a member of the glycol ether acetate family. Its chemical structure, C6H12O3, features both ether and ester functional groups, contributing to its unique solvency profile. Here are some of its most important properties:

  • Appearance: PGMEA is typically described as a clear, colorless liquid. This visual characteristic is important for applications where the aesthetic of the final product matters, such as in certain inks and coatings.
  • Molecular Weight: With a molecular weight of approximately 132.16 g/mol, it falls within the range of commonly handled organic solvents.
  • Boiling Point: The boiling point of PGMEA is around 146-155 °C (depending on the source and pressure). This medium boiling point contributes to its controlled evaporation rate, a critical factor in applications like photoresist coating and high-quality finishes.
  • Flash Point: PGMEA has a flash point of approximately 45-47 °C. This classifies it as a flammable liquid, necessitating appropriate handling and storage precautions in industrial settings.
  • Solubility: PGMEA exhibits limited miscibility with water but is highly soluble in most organic solvents. This amphiphilic nature allows it to dissolve a broad spectrum of organic compounds, including various resins, polymers, and dyes, making it an excellent choice for complex formulations. For instance, its solubility in water is reported as approximately 19.8 g/L at 25 °C.
  • Odor: It is characterized by a mild, ester-like odor, which is generally considered more pleasant and less pungent than some other industrial solvents.
  • Density: Its density is around 0.96 g/cm³, which is typical for organic solvents of its molecular size.

The Impact of Properties on Applications

These properties directly translate into PGMEA’s effectiveness in various industries. Its solvency power makes it ideal for dissolving resins in coatings and inks. Its controlled evaporation rate is crucial for achieving smooth, defect-free films in electronics manufacturing and automotive coatings. The mild odor and relatively low toxicity profile (compared to some alternatives) also contribute to its widespread acceptance in industrial processes.
