Hexamethylenetetramine or methenamine, also known as hexamine or urotropin, is a heterocyclic organic compound with the formula (CH 2) 6 N white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to is useful in the synthesis of other chemical compounds, e.g., plastics, pharmaceuticals, rubber g point: °C ( °F; K) (sublimes).

Adamantane is a colorless, crystalline chemical compound with a camphor-like a formula C 10 H 16, it is a cycloalkane and also the simplest tane molecules consist of three cyclohexane rings arranged in the "armchair" configuration. It is unique in that it is both rigid and virtually stress-free. Adamantane is the most stable among all the isomers with formula C 10 H.

Derivatives in which the amino group was attached to ethyl or propyl side chains at position 3 of the adamantane ring were also effective at inhibiting parasite growth (see data for compounds 2/15, 2/, 2/23, and 2/, Table Table1). 1). These activities, however, could also be dramatically affected by other substitutions on the adamantane by:

A facile synthesis for 1-fluoro(trifluoromethyl)adamantane, based on fluorination of 3-hydroxyadamantanecarboxylic acid, was developed. Its synthetic potentialities for preparation of (trifluoromethyl)adamantane derivatives containing diverse functional groups (acids, amines, etc.) in a bridgehead position, were : Yevheniia Y.

Adamantane-based polymers might find application for coatings of touchscreens, and there are prospects for using adamantane and its homologues in nanotechnology.
For example, the soft cage-like structure of adamantane solid allow incorporation of guest molecules, which can be released inside Chemical formula: C₁₀H₁₆.
Energy Properties of Adamantane Derivatives were evaluated for some compounds by taking into account the literature data on the condensed phase enthalpies of formation and the ΔfHo (g. James L.

It is unique in that it is both rigid and virtually stress-free. Adamantane is the most stable among all the isomers with CAS number: A new synthetic procedure for the preparation of perfluorinated ketones from nonfiuorinated sec-alcohols was developed.
A key step in the synthetic route was a liquid-phase direct fluorination. This project is supported by the Canadian Institutes of Health Research (award #), Alberta Innovates - Health Solutions, and by The Metabolomics Innovation Centre (TMIC), a nationally-funded research and core facility that supports a wide range of cutting-edge metabolomic is funded by Genome Alberta, Genome British Columbia, and Genome Canada, a not-for-profit organization.
In fact, in the liquid-phase direct fluorination process, the reactant is injected at a very slow constant rate into an inert fluorocarbon solvent saturated by fluorine. It is pointed out to be very important that a large excess of F 2 relative to hydrogen atoms to be replaced in a substrate should be maintained.
