Menthol Crystals USP/BP
Synthetic racemic menthol in crystalline form, conforming to USP and BP pharmacopoeial standards. Composed of a 1:1 mixture of D-menthol and L-menthol enantiomers, with specific optical rotation between −2° and 2°, indicating optical inactivity. These crystals are white or colorless with a characteristic peppermint aroma and mild cooling effect (~50% intensity compared to pure L-menthol). Exhibits melting points of 28 °C or 38 °C due to dual crystal forms. Very slightly soluble in water, readily soluble in ethanol, volatile oils, and other organic solvents. Used in topical analgesics, lozenges, decongestants, oral care, cosmetics, food, and industrial applications. Manufactured synthetically under GMP conditions and intended for cost-effective formulations not requiring full L-menthol potency.
Product Specifications
| Chemical Name | DL-Menthol (Racemic Menthol) |
| Synonyms | (±)-Menthol, dl-Menthol, Mentholum racemicum |
| CAS Number | 89-78-1 / 1490-04-6 |
| Molecular Formula | C₁₀H₂₀O |
| Specific Rotation | −2° to 2° (optically inactive) |
| Melting Point | 28 °C or 38 °C |
| Appearance | White crystalline powder or colorless needle-like crystals |
| Odor | Characteristic peppermint |
| Solubility | Slight in water; readily soluble in ethanol and oils |
| Origin | Synthetic |
Applications and Benefits:
- Topical formulations: creams, gels, ointments
- Throat lozenges and nasal inhalers
- Chewing gum, candies, and flavorings
- Toothpaste and mouthwash
- Shampoos, body washes, and lotions
- Cigarette and tobacco flavoring

Caution:
Avoid contact with eyes, skin, and mucous membranes. May cause irritation. Use with proper ventilation and personal protection. Store in a dry, cool area in tightly closed containers between 15 °C and 30 °C. Do not substitute for L-menthol in formulations requiring pure enantiomer. Keep away from oxidizing agents, acids, bases, and ignition sources.

Metal Electrodes, Set Of 6
This set of 6 metal electrodes is ideal for use in electrovoltaic cells or various chemistry and physics experiments. Each electrode is made from different metals, including iron, copper, zinc, aluminum, steel, and magnesium. The electrodes are carefully sized at approximately 120mm x 18mm x 0.75mm (5" x 1/2" x 1/32"), making them easy to handle and suitable for classroom or laboratory use. Their consistent dimensions and material composition ensure reliable performance during experiments. These electrodes are perfect for students, educators, or lab technicians looking to demonstrate electrochemical reactions or explore the properties of different metals in practical experiments.
The set of metal electrodes includes various metals that are commonly used in experiments involving electrovoltaic (or galvanic) cells, electrochemistry, and other physics and chemistry experiments. Here's a brief overview of how these metals might be used:
1. Iron (Fe)
- Properties: Iron is a reactive metal and can oxidize easily.
- Use: Commonly used in electrochemical reactions, such as rusting experiments, or as one electrode in electrochemical cells.
2. Copper (Cu)
- Properties: Copper is a good conductor of electricity and is relatively unreactive compared to other metals.
- Use: Frequently used as a positive electrode in electrovoltaic cells, due to its stability and conductive properties.
3. Zinc (Zn)
- Properties: Zinc is highly reactive and easily gives up electrons.
- Use: Commonly used as the negative electrode in electrochemical cells, like in a simple zinc-copper battery.
4. Aluminum (Al)
- Properties: Aluminum is a lightweight, reactive metal with a natural oxide layer that protects it.
- Use: Often used in chemical reactions to produce hydrogen or as an electrode in electrolytic cells.
5. Steel (an alloy of iron)
- Properties: Steel is more resistant to corrosion than pure iron, thanks to the presence of carbon and sometimes other elements.
- Use: Steel can be used in experiments similar to iron, but it is less prone to rusting.
6. Magnesium (Mg)
- Properties: Magnesium is a highly reactive metal, often used in pyrotechnics due to its bright flame when ignited.
- Use: Magnesium is frequently used in electrochemical cells as a very reactive metal, often as a negative electrode.
Applications:
- Electrovoltaic Cells (Galvanic Cells): You can use these metals to build simple electrovoltaic cells, where two different metals act as electrodes and a solution (electrolyte) allows ions to flow, generating electricity.
- Corrosion and Rusting Experiments: The set can be used to observe how different metals react with the environment (such as exposure to water or air).
- Electrolysis: These metals can be used in electrolysis experiments to separate chemical compounds into their elemental forms using an electrical current.
