Description

Methylglycerin CAS NO 25245-58-3 is a versatile organic compound, a methyl ether derivative of glycerol, valued for its unique combination of hydroxyl functionality and ether stability. This chemical serves as a crucial building block and intermediate, offering enhanced solubility and reactivity profiles compared to its parent alcohol. It is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking to develop advanced formulations and synthesize complex molecules.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, where its ether linkage provides metabolic stability.
• Polymer & Resin Modifier: Acts as a monomer or cross-linking agent in the production of specialty polyethers, polyesters, and alkyd resins, improving flexibility and adhesion.
• Personal Care & Cosmetics: Employed as a humectant, solvent, or carrier in skincare, haircare, and cosmetic formulations due to its hygroscopic and skin-compatible properties.
• Chemical Synthesis Solvent & Reagent: Functions as a polar, high-boiling point solvent and a protected glycol intermediate in organic synthesis reactions.
• Lubricant & Functional Fluid Additive: Incorporated into synthetic lubricants and hydraulic fluids to enhance viscosity index, thermal stability, and moisture control.
• Agrochemical Formulations: Used as a solvent or adjuvant in pesticides and herbicides to improve active ingredient solubility and foliar adhesion.

Quality Control

Our Methylglycerin is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting results from GC, HPLC, and titration methods are provided to guarantee traceability and compliance with your application requirements.

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. Keep away from strong alkalis and incompatible materials.
