Product Overview
o-Cresol LR is a high-quality laboratory reagent-grade chemical designed for precision applications in research and analytical environments. This clear, colorless to pale yellow liquid exhibits a characteristic phenolic odor and boasts a minimum purity of 99%, ensuring reliable and reproducible results in critical experiments. The LR grade designation confirms its suitability for general laboratory use, where consistent performance is essential. With a boiling point of approximately 191°C and a density of 1.048 g/cm³ at 20°C, o-Cresol demonstrates excellent stability under standard lab conditions. Its molecular formula (C₇H₈O) and molecular weight (108.14 g/mol) make it a versatile building block in organic chemistry. The chemical’s solubility in organic solvents like ethanol and ether, combined with its limited water solubility (2.5 g/100 mL at 25°C), allows for precise control in various reaction media. As a monohydric phenol derivative, o-Cresol offers distinct reactivity patterns compared to its para and meta isomers, making it particularly valuable in specialized synthesis routes.
FAQs
1. What is the shelf life of o-Cresol LR when stored properly?
When stored in tightly sealed original containers away from direct sunlight and moisture at room temperature, o-Cresol LR maintains its specified purity for at least 24 months from the date of manufacture. The container should be kept in a well-ventilated area, separate from oxidizing agents and food products.
2. How does o-Cresol LR compare with technical grade o-Cresol?
o-Cresol LR grade offers higher purity (minimum 99%) compared to technical grade (typically 90-95%), making it more suitable for analytical applications and sensitive reactions. The LR grade has stricter controls on impurities like water content, heavy metals, and residual solvents, which could interfere with experimental results or product quality in research settings.
3. Can o-Cresol LR be used as a solvent for polymer synthesis?
Yes, o-Cresol LR can serve as a solvent in certain polymer synthesis applications due to its ability to dissolve various organic compounds and its relatively high boiling point. However, its phenolic nature means it may participate in reactions with some monomers or initiators, so compatibility should be verified through small-scale trials before full implementation.
4. What safety precautions should be taken when handling o-Cresol LR?
o-Cresol LR requires careful handling as it is corrosive to skin and eyes, and harmful if inhaled or ingested. Always use in a fume hood with proper ventilation, wear nitrile gloves, safety goggles, and a lab coat. In case of skin contact, immediately wash with plenty of soap and water and seek medical attention if irritation persists. The chemical should be stored in corrosion-resistant containers with proper labeling.
5. Is o-Cresol LR compatible with glass laboratory equipment?
o-Cresol LR is generally compatible with borosilicate glass laboratory equipment for short-term use. However, prolonged contact may cause slight etching of glass surfaces due to its phenolic nature. For long-term storage or repeated use, consider using containers made of high-density polyethylene (HDPE) or polypropylene, which offer better chemical resistance while maintaining product purity.
