Description

Glycerol Formal CAS NO 68442-91-1 is a versatile, high-purity solvent and chemical intermediate, primarily a mixture of 5-hydroxy-1,3-dioxane and 4-hydroxymethyl-1,3-dioxolane. This compound matters for its excellent solvency, low toxicity, and high boiling point, making it a valuable, safer alternative to more volatile or hazardous solvents. It is needed by manufacturers in the pharmaceutical, agrochemical, and personal care industries for formulating injectables, pesticides, and cosmetic products where purity and performance are critical.

Application

• Pharmaceutical Solvent: Used as a co-solvent in injectable formulations and topical preparations due to its low irritation profile and good solubilizing power.
• Agrochemical Carrier: Serves as a key component in pesticide and herbicide formulations, enhancing the stability and efficacy of active ingredients.
• Cosmetic & Personal Care: Employed in lotions, creams, and other personal care products as a humectant and solvent for fragrances or active compounds.
• Chemical Synthesis: Acts as a protecting group reagent and building block in organic synthesis, particularly for producing specialized polymers and fine chemicals.
• Industrial Cleaner: Utilized in specialty cleaning formulations where a high-boiling, low-volatility solvent is required.
