For research scientists and product developers in the cosmetic and pharmaceutical industries, a deep understanding of ingredient specifications is crucial for successful formulation. D-Panthenol (CAS 81-13-0), a widely utilized provitamin B5, requires careful attention to its quality parameters to ensure optimal product performance and safety. Sourcing from reputable suppliers who clearly define these specifications is a fundamental step.

Key Quality Parameters for D-Panthenol

When you buy D-Panthenol, several key indicators should be examined to verify its quality and suitability for your application:

• Purity: This is perhaps the most critical specification. High-grade D-Panthenol typically boasts a purity of ≥98%. Suppliers should provide assay results, often determined by techniques like HPLC or titration, to confirm this.
• Appearance: High-quality D-Panthenol is described as a viscous, clear liquid, often colorless to pale yellow. Any deviation from this visual characteristic could indicate contamination or degradation.
• Odor: A faint, characteristic odor is typical. Strong or unpleasant odors may suggest the presence of impurities.
• pH: The pH of D-Panthenol solutions is an important factor, particularly for formulations sensitive to acidity or alkalinity. Typical values are around neutral to slightly alkaline.
• Water Content: As a hygroscopic substance, D-Panthenol can absorb moisture. Specifications for water content (often <0.1%) are important for maintaining its stability and concentration.
• Specific Rotation: For D-Panthenol, the optical rotation is a key stereochemical indicator, confirming the correct enantiomer is present. Values typically range around +30°

Understanding CAS 81-13-0

The CAS number 81-13-0 uniquely identifies D-Panthenol, distinguishing it from its enantiomer, L-Panthenol, or the racemic mixture. Ensuring you are sourcing the correct isomer is vital, as D-Panthenol is the biologically active form. Always confirm the CAS number on product datasheets and Certificates of Analysis.
