Product Overview
L-(-) Camphor Sulphonic Acid is a high-purity (99%) crystalline reagent widely recognized for its role as a chiral resolving agent in asymmetric synthesis. Its unique molecular structure, derived from natural camphor, provides excellent solubility in polar solvents while maintaining stability under standard laboratory conditions. The compound exhibits strong acidic properties (pKa ~1.2) due to the sulfonic acid group, making it effective for pH adjustment in organic reactions. The extra pure grade ensures minimal impurities, which is critical for sensitive applications requiring precise stereochemical control. Its solid form allows for easy handling and accurate weighing, while the white to off-white appearance serves as a visual indicator of purity. The product is particularly valued for its ability to form diastereomeric salts with racemic amines, enabling efficient enantiomeric separation. Storage in a cool, dry environment preserves its integrity, as the compound is hygroscopic and may absorb moisture over time.
FAQs
1. What is the melting point of L-(-) Camphor Sulphonic Acid?
The melting point ranges between 195-200°C, though slight variations may occur depending on the heating rate and sample purity.
2. Can this compound be used for non-chiral applications?
Yes, it functions effectively as a general acid catalyst in various organic transformations beyond chiral resolutions.
3. How should I dispose of unused material?
Follow standard laboratory protocols for acidic organic waste disposal, neutralizing with a base before disposal if required.
4. Is this product compatible with common organic solvents?
It dissolves readily in methanol, ethanol, and DMSO but has limited solubility in non-polar solvents like hexane.
5. What alternatives exist for chiral resolution?
Common alternatives include tartaric acid derivatives and mandelic acid, though their effectiveness varies by application.
