Product Name – 1,3-Dioxolane, 99.8%, anhydrous, stabilized with 75 ppm BHT, AcroSeal® Quantity/Pack Size – 1LT, 100ML Form – Liquid Grade – 99.8% Anhydrous Application – Solvent, reagent, chemical synthesis

Product Overview

1,3-Dioxolane, 99.8% anhydrous, is a high-purity cyclic acetal solvent stabilized with 75 ppm BHT to prevent oxidative degradation. Packaged under AcroSeal® technology, this reagent ensures minimal moisture contamination and extended shelf life, making it ideal for demanding laboratory environments. The anhydrous grade guarantees low water content, critical for reactions sensitive to hydrolysis or moisture-induced side reactions. Its stabilized formulation maintains consistency in performance, even during prolonged storage or repeated use. The solvent’s unique chemical structure—combining ether and acetal functionalities—enables versatile applications where polar aprotic solvents are required. The AcroSeal® packaging further enhances safety by reducing exposure to atmospheric moisture during handling. This product is rigorously tested to meet stringent purity standards, ensuring reproducibility in experimental protocols. Whether used as a reaction medium, extraction solvent, or analytical reagent, its high evaporation rate and miscibility with organic solvents provide operational efficiency. The inclusion of BHT as a stabilizer inhibits peroxide formation, addressing common safety concerns associated with ether-based solvents.

FAQs

1. What is the significance of BHT stabilization in 1,3-Dioxolane?

BHT (butylated hydroxytoluene) is added at 75 ppm to inhibit peroxide formation, which can occur in ether-based solvents upon exposure to oxygen or light. This stabilization extends shelf life and reduces hazards associated with peroxide accumulation, such as explosive decomposition during distillation or concentration.

2. How does AcroSeal® packaging benefit this solvent?

AcroSeal® packaging uses a specialized bottle design with a resealable septum cap, minimizing air and moisture ingress. This preserves the anhydrous quality of the solvent, reduces contamination risks, and allows for precise dispensing without repeated opening, which can compromise purity.

3. Is this grade of 1,3-Dioxolane compatible with lithium-aluminum hydride (LAH) reductions?

While 1,3-Dioxolane is less commonly used than THF for LAH reductions, its anhydrous grade and stability make it a viable alternative for certain protocols. However, compatibility should be verified with specific reaction conditions, as trace impurities or stabilization additives may influence outcomes.

4. What storage conditions are recommended to maintain the solvent’s purity?

Store the sealed container in a cool, dry place away from direct sunlight and ignition sources. For long-term storage, keep under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidative degradation. Avoid storing near strong acids or oxidizing agents, which could compromise the BHT stabilizer.

5. Are there lower-purity alternatives available for less critical applications?

Lower-grade 1,3-Dioxolane (e.g., 99% or technical grade) may be suitable for non-sensitive applications like general cleaning or extraction. However, these grades often lack stabilization and may contain higher moisture or impurity levels, making them unsuitable for reactions requiring anhydrous conditions.
