Understanding the fundamental chemistry of materials is key to unlocking their full potential in industrial applications. Mono Hema Phthalate, known by its CAS number 27697-00-3, is a compound that exemplifies the sophistication of modern chemical synthesis and its impact on material properties. This article delves into the chemical structure, physical properties, and synthesis insights of this important reactive monomer, highlighting its significance as a specialty chemical.

Mono Hema Phthalate is chemically known as 1,2-Benzenedicarboxylic acid, 1-[2-[(2-methyl-1-oxo-2-propen-1-yl)oxy]ethyl] ester. Its structure is characterized by a phthalic acid diester derivative where one of the carboxylic acid groups is esterified with a 2-hydroxyethyl methacrylate moiety. This dual functionality is what makes it so valuable. The methacrylate group (2-methyl-1-oxo-2-propen-1-yl) provides a reactive site for radical polymerization, a common method for creating polymers. The phthalate portion contributes to the molecule’s overall properties, such as its solubility and potential plasticizing effects.

Physically, Mono Hema Phthalate is typically described as a clear liquid, often colorless to light yellow. It possesses a relatively high boiling point (around 232°C) and a density of approximately 1.228 g/mL at 25°C. Its solubility is good in many organic solvents, which is advantageous for processing in various chemical formulations. For those seeking to buy 2-(Methacryloyloxy)ethyl hydrogen phthalate, these properties are important considerations for handling and application. The compound's ability to form polymers is central to its use as a reactive monomer for coatings and as an intermediate in polymer synthesis.

While specific industrial synthesis routes are often proprietary, the formation of Mono Hema Phthalate generally involves the esterification of phthalic anhydride or phthalic acid with 2-hydroxyethyl methacrylate. The precise control over reaction conditions is crucial to ensure the selective esterification and achieve high purity. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD., who specialize in providing such chemicals, invest heavily in process optimization to deliver consistent quality. Understanding the chemistry behind this versatile compound allows industries to leverage its unique attributes for innovation in material science and beyond, including its potential as an API intermediate.
