Buy Benzocaine powder online (CAS 94-09-7) from Davechemicals.com is a high-purity research-grade local anaesthetic compound supplied strictly for laboratory, analytical, and forensic applications, not for human or veterinary use, with consistent quality that serious researchers in the UK, USA, Germany, Australia and Asia demand for reproducible results.
🔬 What Is Benzocaine Powder (CAS 94-09-7)?
Benzocaine powder (CAS 94-09-7) is an ester-type local anaesthetic, chemically known as ethyl 4-aminobenzoate, widely used as a reference material in pharmaceutical, analytical, and formulation research. In pharmacology literature, benzocaine is described as a classic sodium channel blocker used to study nociception, membrane excitability, and local anaesthetic structure–activity relationships.
According to data from resources such as DrugBank and PubChem, benzocaine is poorly soluble in water, more soluble in organic solvents, and typically appears as a white to off-white crystalline powder. At Davechemicals.com, our benzocaine powder is supplied strictly for research purposes only, not for human consumption, aligned with our wider catalogue of specialist materials such as lidocaine powder and boric acid magic fishscale flake.
🧪 How Does Benzocaine Powder Work In Research?
Pharmacology sources describe benzocaine as an ester local anaesthetic that blocks voltage-gated sodium channels in neuronal membranes, preventing depolarisation and propagation of action potentials. This action makes benzocaine powder useful in in vitro assays exploring ion channel behaviour, nerve conduction models, and comparative studies with other local anaesthetics.
A paper in the NCBI Bookshelf notes that benzocaine is metabolised mainly by plasma esterases and has a relatively localised action, properties that make it attractive for short-range, surface-focused experimental work. For physicochemical work, suppliers such as TCI Chemicals report a typical melting point in the 89–92 °C range and high assay purity, figures that serious research teams often mirror in their own benzocaine powder specifications.
What Is Benzocaine Powder Used For?
Benzocaine powder is a moderately soluble ester of para-aminobenzoic acid and serves as a local anesthetic in various settings. It appears in numerous over-the-counter products such as skin creams, dry powders for treating skin ulcers, throat lozenges, and even dental preparations for children. Learn more about its applications in The Benefits of Benzocaine Powder as a Local Anesthetic.
Uses:
- Benzocaine powder can be blended into a DIY numbing cream by mixing it with a suitable cream or gel base. This cream may be used to prepare the skin for procedures such as injections, tattooing, waxing, or laser hair removal.
- It can also be applied directly to relieve toothaches, canker sores, and sore throats.
How It Works:
When applied to the skin or gums, benzocaine works by blocking voltage-dependent sodium channels in nerve cells. This interference prevents pain signals from reaching the brain, offering relief for approximately 30–60 minutes. Remember, as a local anesthetic, benzocaine only numbs the area of application; it does not provide systemic anesthesia.
Precautions:
Always use benzocaine powder externally and in modest doses. Excessive use can lead to methemoglobinemia, a serious condition where oxygen transport in the blood is impaired. Perform a patch test on a small skin area before broader application, and avoid using it on broken or inflamed skin.
