Etomidate

CAS 33125-97-2C14H16N2O2Cell Biology

Etomidate (CAS: 33125-97-2; Formula: C14H16N2O2; MW: 244.29 g/mol) is a non-barbiturate hypnotic agent. It functions as a positive allosteric modulator of GABA-A receptors, leading to central nervous system depression. Primarily utilised in anaesthesia for induction, its rapid onset and short duration make it valuable for short procedures and intubation. Available as a white powder, it is supplied by TSS with an assay of >98% HPLC.

01 /Applications

Anaesthetic Agent

Etomidate is employed as an intravenous anaesthetic for the induction of general anaesthesia. Its rapid onset of action and favourable haemodynamic profile make it suitable for patients with unstable cardiovascular conditions.

Sedation

In certain clinical settings, Etomidate can be used for short-term sedation. Its properties allow for controlled induction and recovery, facilitating brief medical interventions.

Neuroscience Research

As a modulator of GABA-A receptors, Etomidate serves as a valuable tool in neuroscience research to investigate inhibitory neurotransmission and neuronal excitability.
