CAS 94-24-6 Tetracaine

CAS 94-24-6 corresponds to Tetracaine, a local anesthetic commonly used in medical and dental procedures. Here is some information about Tetracaine


Quick detail
Tetracaine CAS:94-24-6
Tetracaine MF:C15H24N2O2
Tetracaine MW:264.36
Tetracaine EINECS:202-316-6
Tetracaine Assay:99%
Tetracaine Quality Standards:EnterpriseStandard/Pharma Grade
Tetracaine Appearance:White powder
Tetracaine Usage: Tetracaine is a topical local anesthetic for the eyes. Tetracaine works by interfering with entry of sodium ions into nerve cells. This reduces the ability of nerves to generate an impulse and send pain sensations.

CAS 94-24-6 Tetracaine Description:
(1) In biomedical research, tetracaine is used to alter the function of calcium release channels (ryanodine receptors) that control the release of calcium from intracellular stores. Tetracaine is an allosteric blocker of channel function. At low concentrations, tetracaine causes an initial inhibition of spontaneous calcium release events, while at high concentrations, tetracaine blocks release completely.
(2) Tetracaine is the T in Tac, a mixture of 5 to 12 per cent tetracaine, 5M(per myriad), a half per mille (0.5‰), or .05 per cent (1 part in 2000) , and 4 or 10 per cent hydrochloride used in ear, nose & throat surgery and in the emergemcy department where numbing of the surface is needed rapidly, especially when children have been injured in the eye, ear, or other sensitive locations.
(3) Tetracaine is synthesized from 4-butylaminobenzoic acid. The ethyl ester is formed through an acid-catalyzed esterification reaction. Base-catalyzed transesterification is achieved by boiling the ethyl ester of 4-butylaminobenzoic acid with excess 2-dimethylaminoethanol in the presence of a small amount of sodium ethoxide.

Use of Tetracaine
Tetracaine is a topical local anesthetic for the eyes; works by interfering with entry of sodium ions into nerve cells.

Tetracaine is a potent local anesthetic that works by blocking nerve signals, thereby numbing the area where it is applied. It is often used topically as eye drops or ointment to numb the eye before certain procedures or to relieve eye pain or discomfort.

In addition to its ophthalmic applications, Tetracaine may also be used as a surface anesthesia for other parts of the body, such as the skin or mucous membranes. It provides temporary relief from pain and itching caused by minor cuts, burns, or insect bites.

Tetracaine should only be used under the supervision and guidance of a healthcare professional, as its misuse or excessive use can lead to serious side effects. It is important to follow the prescribed dosage and duration of use as directed by a healthcare provider.
