Product Name – Oxalyl chloride, 2.0M solution in dichloromethane, AcroSeal® Quantity/Pack Size – 100ML, 800ML Form – Liquid (solution in DCM) Grade – AcroSeal® (high-purity, moisture-controlled) Application – Organic synthesis (acid chloride formation, Swern oxidation)
Product Overview
Oxalyl chloride 2.0M solution in dichloromethane (DCM) is a high-purity, moisture-sensitive reagent designed for demanding organic synthesis applications. The AcroSeal® packaging ensures minimal exposure to atmospheric moisture, preserving reactivity and extending shelf life. This solution is standardized at 2.0 molarity, providing consistent performance in acid chloride formation, Swern oxidations, and other chlorinating reactions where precise stoichiometry is critical. The dichloromethane solvent enhances solubility while maintaining compatibility with most organic reaction setups. The sealed format eliminates the need for additional purification steps, reducing workflow contamination risks. Ideal for researchers requiring reproducible results, this solution minimizes side reactions associated with moisture or impurities. The amber glass bottle with PTFE-lined cap further protects against light-induced degradation and solvent evaporation. For best results, store under inert gas and handle in a fume hood due to the corrosive and toxic nature of both oxalyl chloride and DCM.
FAQs
1. What is the exact molarity tolerance for this oxalyl chloride solution?
The 2.0M specification is maintained within ±0.1M tolerance, as verified by titration against standardized bases during quality control. Batch-specific certificates of analysis provide exact values.
2. Can this solution be used directly for Swern oxidations without further drying?
Yes, the AcroSeal® packaging and moisture-controlled production process ensure the solution meets the anhydrous requirements for Swern oxidations. No additional drying agents are necessary.
3. What alternatives exist if dichloromethane is not compatible with my reaction?
For DCM-sensitive systems, consider preparing fresh oxalyl chloride solutions in alternative solvents like 1,2-dichloroethane or chloroform, though stability and reactivity may vary.
4. How should I dispose of excess solution or empty containers?
Neutralize excess solution with sodium bicarbonate or calcium hydroxide slurry in a fume hood, then dispose as hazardous waste. Rinse empty containers with acetone before disposal, following local chemical waste regulations.
5. Why does the solution sometimes develop a yellow tint during storage?
Prolonged storage, especially under light exposure, can cause slight decomposition leading to discoloration. While minor tinting doesn’t significantly affect reactivity, we recommend using freshly opened bottles for critical applications.
