Product Overview

This anhydrous acetonitrile (99.5%+ purity) is a high-performance solvent engineered for demanding laboratory applications where trace moisture can compromise results. With a maximum water content of 0.005%, it eliminates interference in HPLC and LC-MS systems, ensuring baseline stability and reproducible separations. The solvent’s exceptional UV transparency (cutoff <190 nm) makes it ideal for photometric detection, while its low viscosity (0.34 cP at 25°C) enables efficient column performance. The product undergoes rigorous distillation and molecular sieve treatment to remove polar impurities, resulting in a solvent with consistent retention times and minimal ghost peaks. Its high dielectric constant (37.5) and dipole moment (3.92 D) provide excellent solvation power for polar and nonpolar compounds alike. The sealed 4-liter container features a tamper-evident cap and nitrogen headspace to prevent moisture ingress during storage. Each batch includes a certificate of analysis with GC/MS purity verification and residual water content data, guaranteeing lot-to-lot consistency for critical applications.

FAQs

1. What is the difference between anhydrous and regular acetonitrile?

Anhydrous acetonitrile contains less than 0.005% water compared to standard grades which may have 0.05-0.2% water content. This ultra-low moisture specification prevents column degradation and baseline drift in sensitive chromatographic applications.

2. Can this solvent be used with UHPLC systems?

Yes, the 99.5%+ purity and sub-0.005% water content make it fully compatible with ultra-high performance liquid chromatography systems operating at pressures up to 15,000 psi.

3. What is the shelf life when stored properly?

When kept in the original sealed container at room temperature (15-25°C) away from direct sunlight, the product maintains its specifications for 24 months from the date of manufacture.

4. Does this product contain any stabilizers or additives?

This is a pure solvent without added stabilizers. The high purity is maintained through advanced distillation processes and nitrogen blanketing during packaging.

5. What packaging materials are used for the 4-liter container?

The solvent comes in a high-density polyethylene container with a polypropylene screw cap and PTFE-faced seal to prevent solvent leakage and atmospheric contamination.
