Description

1-Hydroxymethyl-5,5-Dimethylhydantoin is a versatile and reactive chemical intermediate, primarily valued for its ability to act as a formaldehyde donor and a source of the hydantoin ring system. This compound is crucial for manufacturers requiring controlled-release chemistry and stable heterocyclic building blocks. It is particularly needed by industries involved in the production of specialty polymers, personal care preservatives, and high-performance biocides.

Application

• As a key monomer or cross-linking agent in the synthesis of specialty formaldehyde-release polymers for coatings and resins.
• As a precursor or active ingredient in the formulation of industrial biocides and preservatives for paints, adhesives, and metalworking fluids.
• In the synthesis of quaternary ammonium compounds (quats) with enhanced stability for disinfectant and surfactant applications.
• As a chemical building block for pharmaceutical intermediates and active pharmaceutical ingredients (APIs) containing the hydantoin moiety.
• In the production of hair care and cosmetic ingredients, where it functions as a conditioning agent or preservative booster.
• For research and development of novel antimicrobial agents and materials with controlled-release properties.

Quality Control

Our 1-Hydroxymethyl-5,5-Dimethylhydantoin is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, identity, and performance. Certificates of Analysis (COA) detailing key parameters such as assay, formaldehyde content, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect product stability and handling properties.
