VWR Salicylic Acid is a white crystalline solid with a high purity of ≥99.0%, available in two high-quality reagent grades:
- AnalaR NORMAPUR® for analytical and laboratory applications
- GPR RECTAPUR® for preparative and industrial use
Salicylic acid is a monohydroxybenzoic acid used extensively in analytical chemistry, pharmaceutical synthesis, cosmetics, and organic synthesis. Its excellent solubility in organic solvents and precise melting point make it a standard for calibration and purity testing.
Key Features and Benefits
- ≥99.0% Assay for reliable analytical accuracy and reproducibility
- Low Heavy Metal Content (≤10 ppm as Pb) to minimize contamination
- Complies with AnalaR NORMAPUR® and GPR RECTAPUR® specifications
- Low water content and minimal insolubility in methanol/NH₃
- Stable under ambient storage conditions
- High melting point consistency (158–161 °C range)
Applications
- Preparation of pharmaceutical intermediates (e.g., aspirin)
- Analytical standard in purity assays
- Keratolytic agent base in cosmetics and dermatological formulations
- Precursor in organic and fine chemical synthesis
- Acid-base titrations and quality control procedures
