Hydroxyethyl starch (HES/HAES), sold under the brand name Voluven among others, is a nonionic starch derivative, used as a volume expander in intravenous therapy.The use of HES on critically ill patients is associated with an increased risk of death and kidney problems.
Its sodium salt can be prepared from the chloride: [6] (C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. The use of tritylsodium as a strong, non-nucleophilic base has been eclipsed by the popularization of butyllithium and related strong bases. The unmodified anion is red, and can be used as an indicator in acid–base titrations. Derived ...

Triphenylmethylsodium can be prepared from trityl chloride dissolved in an aprotic solvent and sodium: [4] (C 6 H 5) 3 CCl + 2 Na → (C 6 H 5) 3 CNa + NaCl. Reaction with silver hexafluorophosphate gives triphenylmethyl hexafluorophosphate. Trityl chloride reacts with zinc in nonpolar solvents (e.g. benzene) to form Gomberg's dimer. [5]
Hexobarbital or hexobarbitone, sold both in acid and sodium salt forms as Citopan, Evipan, and Tobinal, is a barbiturate derivative having hypnotic and sedative effects. It was used in the 1940s and 1950s as an agent for inducing anesthesia for surgery, as well as a rapid-acting, short-lasting hypnotic for general use, and has a relatively fast onset of effects and short duration of action.

Trimethyltin chloride is used as a source of the trimethylstannyl group ((CH 3) 3 Sn−). [4]For example, it is a precursor to vinyltrimethylstannane ((CH 3) 3 SnCH=CH 2) [5] and indenyltrimethylstanane (CH 3) 3 SnC 9 H 7 (see Transition metal indenyl complex): [6]
Sodium thiopental was a core medicine in the World Health Organization's List of Essential Medicines, [4] but was supplanted by propofol. [5] [6] [7] Despite this, thiopental is listed as an acceptable alternative to propofol, depending on local availability and cost of these agents. [7]
