Product Overview
Aniline LR is a high-purity laboratory reagent designed for demanding chemical applications where precision and consistency are critical. This clear, colorless to pale yellow liquid is a primary aromatic amine with a distinct odor, widely recognized for its reactivity and versatility in organic synthesis. Its laboratory reagent (LR) grade ensures minimal impurities, making it suitable for sensitive analytical procedures, including titration, spectrophotometry, and chromatographic techniques. The reagent is stabilized to prevent oxidation, maintaining its integrity over extended storage periods when handled under recommended conditions. Its molecular structure (C6H5NH2) allows for efficient participation in nucleophilic substitution, condensation, and diazotization reactions, which are fundamental in synthetic chemistry. The 500 ml packaging provides an optimal balance between bulk efficiency and ease of handling, reducing the need for frequent replenishment while minimizing waste. Compatibility with standard glassware and common organic solvents further enhances its practicality in diverse lab setups. Whether used as a building block in pharmaceutical intermediates or as a calibration standard, this Aniline LR delivers reliable performance with batch-to-batch consistency, backed by rigorous quality control measures.
FAQs
1. What is the shelf life of Aniline LR when stored properly?
When stored in a tightly sealed container away from light, heat, and moisture, Aniline LR maintains its stability for up to 24 months from the date of manufacture. Regularly check for any color changes or sediment formation before use.
2. Can this Aniline LR be used directly in HPLC or GC applications?
While Aniline LR is of high purity, it may require further filtration or distillation depending on the specific sensitivity of your HPLC or GC method. Always validate with a blank run to confirm compatibility with your instrumentation.
3. What precautions should be taken when handling Aniline LR?
Aniline LR is toxic if inhaled, ingested, or absorbed through the skin. Always wear nitrile gloves, safety goggles, and work in a fume hood. Avoid contact with oxidizing agents and strong acids to prevent violent reactions.
4. Is this product compatible with plastic containers for long-term storage?
Aniline LR should be stored in glass containers with PTFE-lined caps to prevent leaching or degradation. Prolonged storage in plastic, especially polyethylene or polypropylene, may lead to contamination or permeability issues over time.
5. How does the LR grade differ from AR or ACS grades in terms of impurities?
The LR (Laboratory Reagent) grade is suitable for general lab use with controlled impurity levels, while AR (Analytical Reagent) and ACS (American Chemical Society) grades undergo stricter purification for trace analysis. LR grade may contain slightly higher residual solvents or metals but remains effective for most synthetic and qualitative applications.
