Product Overview
Diethyl oxalate is a colorless, low-viscosity liquid widely used as a key reagent in organic synthesis. With a purity of 99%+, this laboratory-grade compound ensures reliable results in esterification reactions, serving as a versatile building block for pharmaceutical, agrochemical, and specialty chemical production. Its stable molecular structure (C6H10O4) and low moisture content (<0.1%) minimize side reactions, making it ideal for sensitive applications. The compound’s high boiling point (185°C) allows for controlled reaction conditions, while its miscibility with common organic solvents (ethanol, acetone, ether) enhances versatility. Packaged in airtight, amber glass bottles to prevent photodegradation, this reagent maintains integrity during storage and transport. Complies with standard lab safety protocols for handling esters, with a flash point of 75°C for safe usage in fume hoods. Suitable for both small-scale research and pilot production, offering consistent batch-to-batch performance for reproducible outcomes.
FAQs
1. What is the shelf life of diethyl oxalate when stored properly?
Unopened bottles retain full potency for 24 months from manufacture when stored at 15-25°C in a dry, ventilated area away from direct sunlight and oxidizing agents.
2. Can this reagent be used directly in Grignard reactions?
Yes, its high purity and anhydrous nature make it compatible with Grignard reagents, though pre-drying with molecular sieves is recommended for moisture-sensitive reactions.
3. What alternatives exist for esterification if diethyl oxalate is unavailable?
Dimethyl oxalate or oxalyl chloride can substitute in some applications, but reaction conditions and product yields may vary due to differing reactivity profiles.
4. How should spills of diethyl oxalate be handled in the lab?
Absorb with inert material like vermiculite, then neutralize with sodium bicarbonate solution before disposal as hazardous waste according to local regulations.
5. Does this product contain any stabilizers or additives?
This is a pure reagent without added stabilizers, though trace amounts of ethanol (<0.5%) may occur as a residual solvent from synthesis.
