Product Overview

(±)-Propylene Oxide, 99.5% extra pure, is a highly reactive epoxide supplied in AcroSeal® packaging to ensure stability and minimize contamination. This colorless liquid features a high degree of purity, making it suitable for demanding chemical applications where precision and consistency are critical. The extra pure grade guarantees minimal impurities, including water content, which is essential for reactions sensitive to moisture or catalytic interference. Its molecular structure, containing both an epoxide ring and a chiral center, enables versatile reactivity in nucleophilic substitutions, ring-opening polymerizations, and as a building block in pharmaceutical and agrochemical synthesis. The AcroSeal® technology provides an additional layer of protection against oxidation and atmospheric exposure, extending shelf life without compromising quality. With a boiling point of 34°C and miscibility in most organic solvents, this reagent offers ease of handling in controlled lab environments. The 100ML and 800ML pack sizes cater to both small-scale experiments and bulk requirements, ensuring cost-effective usage across different project scales.

FAQs

1. What is the shelf life of (±)-Propylene Oxide 99.5% in AcroSeal® packaging?

The AcroSeal® packaging extends the shelf life to 24 months when stored unopened at room temperature, away from direct sunlight and ignition sources. Once opened, use within 6 months for optimal purity.

2. Is this grade compatible with anhydrous reaction conditions?

Yes, the extra pure grade with 99.5% purity and low moisture content (typically <0.05%) makes it suitable for anhydrous reactions, though additional drying may be required for ultra-sensitive applications.

3. Can this product be used as a substitute for ethylene oxide in polymerization?

While both are epoxides, propylene oxide introduces a methyl group that alters the polymer properties. It can substitute ethylene oxide in some copolymerizations but may require adjusted reaction parameters.

4. What precautions are needed for storage to prevent degradation?

Store in a cool, well-ventilated area below 25°C, away from oxidizing agents, acids, and bases. Keep containers tightly sealed and use explosion-proof refrigeration if storing large quantities.

5. Does the AcroSeal® packaging affect the product’s reactivity compared to standard bottles?

The AcroSeal® packaging is chemically inert and does not interact with the epoxide. It primarily enhances stability by reducing exposure to oxygen and humidity, preserving reactivity.
