Product Overview

n-Butyl Acetate GC Reference Standard is a high-purity solvent designed for precise chromatographic applications, ensuring reliable and reproducible results in analytical laboratories. This reference-grade material meets stringent quality controls, with a minimum assay of 99.5% and ultra-low impurity levels, making it ideal for calibration, method validation, and quality assurance protocols. Its consistent boiling point (126–127°C) and low water content (<0.05%) minimize variability in retention times, while the absence of stabilizers or additives guarantees interference-free performance. Packaged in amber glass bottles with PTFE-lined caps, it prevents contamination and degradation from light or moisture. The solvent’s low residual evaporation and high volatility further enhance its suitability for gas chromatography (GC) and headspace analysis. Compatible with most organic solvents, it serves as a benchmark for comparing sample purity or instrument performance. Whether used as a standalone standard or in multi-component mixes, its stability and batch-to-batch uniformity reduce recalibration needs, saving time and resources in high-throughput labs.

FAQs

1. What is the shelf life of n-Butyl Acetate GC Reference Standard?

The shelf life is 24 months from the date of manufacture when stored unopened in a cool, dry place away from direct sunlight. Always check the label for the exact expiry date.

2. Can this standard be used for HPLC applications?

While primarily designed for GC, it can be used in HPLC if the method tolerates its volatility. However, a dedicated HPLC-grade solvent may be preferable for optimal UV transparency.

3. How should I dispose of unused or expired n-Butyl Acetate?

Dispose of according to local regulations for flammable organic solvents. Incineration or licensed chemical waste disposal services are recommended. Never pour down drains.

4. Is this product compatible with plastic containers for storage?

Long-term storage in plastic is not advised due to potential leaching or permeation. Use the original glass bottle or transfer to a chemically resistant HDPE container for short-term use.

5. What alternatives exist if this standard is unavailable?

Ethyl acetate or isobutyl acetate GC standards can substitute in some applications, but retention times and selectivity may differ. Always validate alternatives with your specific method.
