Product Overview

This 1,4-Dioxane is a high-purity (99.5%) solvent that has been meticulously dried over molecular sieves and stabilized for consistent performance in demanding laboratory applications. The extra-dry formulation ensures minimal water content, making it particularly suitable for reactions where trace moisture could compromise results. Packaged under nitrogen in AcroSeal® bottles, this solvent maintains its purity during storage and handling. The stabilization process prevents peroxide formation, enhancing safety during long-term use. Its low viscosity and excellent solvency power make it a preferred choice for dissolving both polar and nonpolar compounds. The product’s high boiling point (101°C) allows for extended reaction times at elevated temperatures without significant evaporation loss. This grade meets stringent quality control standards, with batch-specific certificates of analysis available to verify its specifications.

FAQs

1. What does “extra dry over molecular sieve” mean for this 1,4-Dioxane?

The molecular sieve treatment indicates this solvent has been processed to remove water to extremely low levels, typically below 50 ppm, ensuring anhydrous conditions for moisture-sensitive applications.

2. How does the AcroSeal® packaging benefit this product?

AcroSeal® bottles feature a special septum that allows for airtight storage and contamination-free dispensing, maintaining the solvent’s purity throughout its shelf life.

3. What precautions should be taken when handling this stabilized 1,4-Dioxane?

While stabilized, it should still be stored in a cool, well-ventilated area away from ignition sources, and standard solvent handling procedures should be followed.

4. Is this grade suitable for HPLC applications?

Yes, the 99.5% purity and low water content make it appropriate for HPLC use, though UV-cutoff specifications should be verified for specific detection requirements.

5. How does the stabilization process affect the solvent’s properties?

The stabilization prevents peroxide formation that could occur during storage, maintaining the solvent’s original properties and extending its usable shelf life.
