Product Overview
N,N-Dimethylaniline LR is a high-purity laboratory reagent designed for demanding chemical applications where precision and consistency are critical. This colorless to pale yellow liquid features a minimum assay of 99%, ensuring reliable performance in synthesis reactions, analytical procedures, and as a key intermediate in dye manufacturing. Its low moisture content (<0.1%) and tightly controlled specifications make it particularly suitable for applications requiring stringent quality control. The reagent’s stability under standard laboratory conditions, combined with its compatibility with common organic solvents, allows for seamless integration into existing protocols. Packaged in 500 ml amber glass bottles to prevent light-induced degradation, this LR-grade dimethylaniline maintains its integrity throughout storage and handling. The product undergoes rigorous quality testing to meet international laboratory standards, with certificates of analysis available for each batch. Its balanced viscosity and controlled boiling point (193-194°C) facilitate precise measurement and consistent reaction kinetics across various experimental setups.
FAQs
1. What is the typical shelf life of N,N-Dimethylaniline LR when stored properly?
When stored in its original tightly sealed container at room temperature, away from direct sunlight and moisture, N,N-Dimethylaniline LR maintains its specified purity for at least 24 months from the date of manufacture. The amber glass bottle provides additional protection against light-induced degradation.
2. How does the LR grade differ from technical or analytical grades of dimethylaniline?
The LR grade is specifically purified to meet laboratory reagent standards, with tighter controls on impurities (typically <0.5% total) compared to technical grade. While not as stringent as analytical grade, it offers a balanced combination of purity and cost-effectiveness for most synthetic applications where ultra-high purity isn’t critical.
3. What precautions should be taken when handling this chemical in a standard lab setting?
Standard laboratory safety measures should be followed, including working in a fume hood, wearing nitrile gloves, and using safety goggles. The chemical is known to cause skin irritation and should be handled with care to avoid inhalation of vapors, particularly when working with larger quantities or at elevated temperatures.
4. Can this product be used as a solvent in chromatographic applications?
While N,N-Dimethylaniline can serve as a solvent in certain chromatographic systems, its relatively high boiling point and potential UV absorbance may limit its suitability for some HPLC or GC applications. For chromatographic use, we recommend verifying compatibility with your specific detection method and column chemistry.
5. What is the recommended disposal method for unused or expired N,N-Dimethylaniline?
Unused or expired material should be collected in appropriate chemical waste containers and disposed of through licensed hazardous waste handlers according to local environmental regulations. Never dispose of this chemical by pouring down drains or mixing with general laboratory waste due to its potential environmental persistence.
