Who this is best for: researchers who need verified chemical identity and a straightforward bulk option. Caution: packaging may vary and could differ from the pictured item.
Albochemicals Benzocaine High Purity 50 g
Brand: Albochemicals. This 50-gram option also centers on CAS 94-09-7 and notes possible packaging variation. Best for phased experiments with moderate material needs.
Who this is best for: labs with staged testing plans and limited space requiring smaller, consistent batches. Limitation: packaging may differ from the image in listings.
Erbium Oxide Powder 10 g (Nano, 99.9%)
Brand: Generic. Features include 99.9% purity, 20 nm particle size, and CAS 12061-16-4. Best for comparative research or specialized applications in ceramics and glass coloring.
Who this is best for: researchers exploring materials science or colorants who want a high-purity rare-earth oxide. Caution: not a benzocaine product; use only if the research context requires rare-earth oxide powders.
Zirconium Metal Granules 10 g
Brand: Generic. Features include 99.9%+ purity and 3-micron particle size notes; vacuum packing recommended to maintain appearance. Best for specialized lab experiments and specimen collection in metal studies.
Who this is best for: labs needing tiny quantities of high-purity zirconium for elemental experiments. Caution: not benzocaine; relevance limited to total powder portfolio and comparative studies.
Buying Guide: Benzocaine Powder 99.9% For Formulation And Research
- Purity matters: Look for products explicitly stating 99.9% or higher purity and confirm CAS numbers (for benzocaine, CAS 51-78-5).
- Quantity vs. project scale: Choose 25 g for pilot tests, 50–100 g for ongoing formulation work. Plan storage for larger packs to avoid degradation.
- Packaging consistency: Expect variations in labeling or packaging. Verify lot numbers and certificates if you require traceability.
- Intended use: For topical numb cream development, prioritize ultra-fine or ultra-pure grades that dissolve consistently in carriers.
- Safety and handling: Follow standard chemical handling practices and ensure proper PPE, ventilation, and labeling in your lab.
- Alternative materials: The guide includes other high-purity powders for context. Use them only if your project involves comparative studies with materials beyond benzocaine.
Frequently Asked Questions
