Product Overview

1,2-Pentanediol is a high-purity diol compound widely used in laboratory settings as a solvent, reagent, and intermediate in organic synthesis. Its unique chemical structure, featuring two hydroxyl groups, provides excellent solubility for polar and non-polar compounds, making it a preferred choice for extractions, chromatography, and reaction media. This laboratory-grade 1,2-Pentanediol exhibits low volatility, reducing evaporation losses during prolonged experiments, while its hygroscopic nature ensures consistent performance in moisture-sensitive applications. The reagent is compatible with a broad range of organic solvents, including alcohols, ethers, and chlorinated hydrocarbons, enabling seamless integration into multi-step synthetic protocols. Its moderate boiling point (206°C) allows for easy recovery via distillation, enhancing cost-efficiency in large-scale processes. The product is rigorously tested for purity, with minimal residual water content and absence of heavy metal contaminants, ensuring reliable and reproducible results. Packaged in high-density polyethylene (HDPE) bottles with tamper-evident seals, it maintains stability under standard lab storage conditions. Whether used as a co-solvent in nanoparticle synthesis or a mobile phase modifier in HPLC, this 1,2-Pentanediol delivers consistent performance across diverse analytical and preparative applications.

FAQs

1. What is the shelf life of 1,2-Pentanediol when stored properly?

When stored in a tightly sealed container at room temperature, away from direct sunlight and moisture, 1,2-Pentanediol typically retains its specified purity for 24 months from the date of manufacture.

2. Can this grade of 1,2-Pentanediol be used in GC or HPLC analysis?

This laboratory-grade 1,2-Pentanediol is suitable for general HPLC applications as a mobile phase modifier, though for ultra-sensitive GC analysis, further purification via distillation may be recommended to remove potential trace impurities.

3. Is this product compatible with glassware and standard lab plastics?

1,2-Pentanediol is compatible with borosilicate glass and most lab-grade plastics including PP, HDPE, and PTFE. Prolonged contact with polystyrene or PVC should be avoided as it may cause swelling or degradation over time.

4. What precautions should be taken when handling 1,2-Pentanediol?

While not classified as highly hazardous, standard lab precautions apply: wear nitrile gloves, safety goggles, and work in a well-ventilated area. Avoid inhalation of vapors and skin contact, as it may cause mild irritation in sensitive individuals.

5. How does 1,2-Pentanediol compare to 1,5-pentanediol in solvent applications?

1,2-Pentanediol offers higher polarity and hydrogen-bonding capacity due to the proximity of its hydroxyl groups, making it more effective for dissolving polar compounds. 1,5-Pentanediol, with its spaced hydroxyl groups, tends to have lower viscosity and may be preferred in applications requiring faster diffusion rates.
