Product Overview

Tetrahydrofuran (THF) reference standard is a high-purity, anhydrous solvent designed for critical laboratory applications where precision and consistency are paramount. This grade ensures minimal water content (typically <0.005%) and a purity level of 99.9%, making it suitable for use as a reference material in gas chromatography (GC) and high-performance liquid chromatography (HPLC). The solvent is stabilized with butylated hydroxytoluene (BHT) to prevent peroxide formation, extending its shelf life and maintaining reliability in long-term storage. Its low UV absorbance and high volatility further enhance its utility in spectroscopic and analytical techniques. Packaged in amber glass bottles to prevent light-induced degradation, this THF reference standard adheres to strict quality control measures, ensuring batch-to-batch consistency. The sealed packaging includes a tamper-evident cap to guarantee integrity upon delivery. Compatible with most organic solvents, it serves as an essential benchmark for calibration curves, method validation, and quality assurance protocols in research and industrial laboratories.

FAQs

1. What is the shelf life of this tetrahydrofuran reference standard?

The shelf life is 24 months from the date of manufacture when stored unopened in its original packaging at room temperature, away from direct sunlight and moisture. Once opened, use within 6 months for optimal performance.

2. Is this THF reference standard compatible with plastic containers?

No, tetrahydrofuran can dissolve or degrade many plastics, including polyethylene and polypropylene. Always store and handle it in glass containers to prevent contamination or container failure.

3. Can this be used as a substitute for HPLC-grade THF?

While it meets high purity standards, this reference standard is specifically formulated for calibration and analytical referencing. For mobile phase preparation in HPLC, use HPLC-grade THF to avoid potential interference from stabilizers like BHT.

4. How should I dispose of unused or expired tetrahydrofuran reference standard?

Dispose of it as hazardous chemical waste according to local environmental regulations. Neutralize small quantities with a compatible absorbent, then incinerate in a licensed facility. Never pour it down drains or discard in regular trash.

5. Does this product contain any stabilizers, and if so, what are they?

Yes, it contains butylated hydroxytoluene (BHT) at a concentration of ~250 ppm as a stabilizer to inhibit peroxide formation, which can occur upon exposure to air or light over time.
