Product Overview
Methyl acetate, 99%+ purity in extra dry grade, is a high-performance solvent designed for applications requiring minimal moisture interference. The AcroSeal® packaging ensures long-term stability by preventing atmospheric moisture absorption, making it ideal for critical laboratory processes. This volatile ester exhibits excellent solvency power for polar and nonpolar compounds while maintaining a low boiling point (57°C), enabling rapid evaporation without residue. The extra dry specification guarantees water content below 50 ppm, eliminating the need for additional drying steps in sensitive protocols. Its low toxicity profile compared to other solvents like dichloromethane makes it a safer alternative for routine lab use. The molecular structure (CH₃COOCH₃) provides balanced polarity, facilitating efficient extractions and chromatographic separations. Each batch undergoes rigorous GC analysis to verify purity, with certificates of analysis available upon request. The amber glass bottles with PTFE-lined caps prevent both moisture ingress and solvent leakage during storage.
FAQs
1. What is the maximum water content in this extra dry methyl acetate?
The extra dry grade guarantees water content below 50 ppm, verified through Karl Fischer titration.
2. Can this be used as a direct replacement for ethyl acetate in existing protocols?
While similar, methyl acetate has a lower boiling point (57°C vs 77°C) and slightly different polarity, so minor protocol adjustments may be needed.
3. How does AcroSeal® packaging differ from standard bottles?
AcroSeal® features a specialized septum and valve system that actively prevents moisture ingress during storage and dispensing.
4. What is the typical shelf life when stored unopened?
When stored in the original AcroSeal® packaging at room temperature, the product maintains specifications for 24 months from manufacture date.
5. Are there any known incompatibilities with common lab materials?
Methyl acetate may degrade certain plastics like polystyrene; use glass or PTFE containers for long-term storage.
