For many fine chemicals and advanced material products, achieving higher purity is far from straightforward. Some materials have high boiling points that make distillation impractical. Others are highly sensitive to solvent systems, making recrystallization screening both costly and time-consuming. In…
When developing a purification process, the most direct way to evaluate a technology is through data. However, when assessing melt crystallization performance, the final product purity alone does not tell the whole story. Equally important is understanding how purity improves…
When conducting laboratory-scale melt crystallization studies, one question frequently arises: customers want to know as early as possible whether a material is worth scaling up. This is where laboratory-scale data becomes critical. The purpose of a lab-scale study is not…
Definition Lactide is a cyclic diester formed through the condensation of two molecules of α-hydroxy acids, most commonly lactic acid. During the reaction, two molecules of water are removed, producing a six-membered heterocyclic compound. Among various lactides, the most commercially…
Definition Glycolic acid, also known as hydroxyacetic acid, is the simplest member of the alpha-hydroxy acid (AHA) family. With the chemical formula CH₂OHCOOH, it contains both a hydroxyl group and a carboxyl group, giving it the ability to participate in…
Definition Lactic acid, also known as 2-hydroxypropanoic acid or α-hydroxypropionic acid, is an organic acid containing both hydroxyl and carboxyl functional groups. It appears as a colorless to pale yellow syrup-like liquid or solid and is widely used in food,…
Definition Methyl Methacrylate (MMA), chemically known as methyl methacrylate, is an unsaturated ester derived from methacrylic acid. It is a colorless, transparent liquid with a characteristic odor and is one of the most important monomers used in polymer and plastics…
