Product Overview
m-Cresol 99% AR is a high-purity analytical reagent designed for critical laboratory applications where precision and consistency are paramount. This colorless to pale yellow liquid belongs to the phenol family, exhibiting strong solvent properties and compatibility with a wide range of organic compounds. Its 99% purity ensures minimal impurities, making it ideal for synthesis reactions, chromatographic analysis, and as a key intermediate in pharmaceutical and chemical research. The AR grade certification guarantees adherence to strict quality standards, with low moisture content and negligible residual metals or contaminants. Its moderate boiling point (202°C) and miscibility with alcohols, ethers, and hydrocarbons enhance its versatility in extraction processes and as a reaction medium. The reagent is packaged in amber glass bottles to prevent photodegradation, preserving its stability during storage. Non-corrosive to glass and most metals under standard conditions, it requires basic ventilation during handling due to its characteristic phenolic odor. For long-term storage, keep the container tightly sealed in a cool, dry place away from oxidizing agents to maintain its analytical integrity.
FAQs
1. What is the shelf life of m-Cresol 99% AR when stored properly?
When stored in its original amber glass bottle at room temperature (15–25°C), away from direct sunlight and moisture, m-Cresol 99% AR retains its specified purity for up to 24 months from the date of manufacture. Always check the label for the exact expiry date.
2. Can this grade of m-Cresol be used for HPLC or GC analysis?
Yes, the AR grade designation indicates that this m-Cresol meets the purity requirements for high-performance liquid chromatography (HPLC) and gas chromatography (GC) applications. However, for ultra-trace analysis, additional filtration or purification may be required depending on the specific method sensitivity.
3. Is m-Cresol 99% AR compatible with plastic labware?
m-Cresol can degrade certain plastics, particularly polystyrene and polycarbonate, over prolonged exposure. For accurate results, use glass or PTFE (polytetrafluoroethylene) labware when handling or storing solutions containing m-Cresol to avoid leaching or contamination.
4. How does m-Cresol differ from o-Cresol or p-Cresol in lab applications?
The three isomers (ortho, meta, para) vary in their physical properties and reactivity. m-Cresol has a higher boiling point (202°C) compared to o-Cresol (191°C) and p-Cresol (202°C but with different solubility profiles). In synthesis, m-Cresol is often preferred for its balanced reactivity in electrophilic substitutions and lower toxicity compared to o-Cresol.
5. What safety precautions should be taken while handling m-Cresol 99% AR?
Always wear nitrile gloves, safety goggles, and a lab coat when handling m-Cresol, as it can cause skin and eye irritation. Work in a fume hood or well-ventilated area to avoid inhaling vapors. In case of spills, absorb with inert material like sand and neutralize with a dilute alkali solution before disposal as hazardous waste.
