Description

3-Hydroxymethylpentane-1,5-Diol is a versatile polyfunctional diol characterized by its two primary hydroxyl groups and one hydroxymethyl group, offering unique reactivity and solubility properties. This compound is valued for its role as a building block in polymer synthesis and as a modifier for enhancing material properties. It is primarily needed by manufacturers in the polymer, coatings, and specialty chemical industries seeking to develop products with tailored hydrophilicity, cross-linking density, and flexibility.

Application

• Polymer Synthesis: Serves as a monomer or co-monomer in the production of polyesters, polyurethanes, and alkyd resins, contributing to chain flexibility and hydroxyl functionality.
• Coatings and Inks: Used as a polyol component in coating formulations to improve adhesion, flexibility, and curing characteristics.
• Cross-linking Agent: Functions as a cross-linker in thermosetting resins, enhancing network density and thermal stability.
• Pharmaceutical Intermediates: Employed as a chiral building block in the synthesis of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Personal Care Products: Can be utilized in the formulation of humectants and moisturizers due to its hygroscopic and polyol nature.
• Adhesives and Sealants: Acts as a modifier to adjust the viscosity, tack, and final mechanical properties of adhesive formulations.

Quality Control

Our 3-Hydroxymethylpentane-1,5-Diol is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality.
