Soluble in water, ethanol, chloroform and acetone.


Hexamethylenetetramine is used as a formylation agent in the synthesis and as a precipitating agent. It is also used in the production of phenolic resins and its moulding compounds, which finds application as binders in fire proof materials, brake and clutch linings. It is involved in the preparation of 5-tert-butyl-2-hydroxy-isophthalaldehyde. It is useful for the treatment of urinary tract infection. Further, it is used in the Duff reaction, Sommelet reaction and in the Delepine reaction.


Hygroscopic. Incompatible with strong oxidizing agents and strong acids. Avoid conditions like flames, sparks and moisture.

For a review of applications in organic synthesis, see: Synthesis, 161 (1979).

Benzylic halides form quaternary salts with hexamine which undergo oxidation during hydrolysis to give aldehydes (Sommelet reaction): Org. React., 8, 197 (1954); Org. Synth. Coll., 3, 811 (1955); 4, 690, 918 (1963). Benzylamines can also be converted to benzaldehydes; see e.g.: Org. Synth. Coll., 5, 668 (1973).

The reaction can also be carried out to give the primary amine on hydrolysis (Delepine reaction). For conversion of allylic halides to amines, see, e.g.: Org. Synth. Coll., 5, 121 (1973); 9, 666 (1998).

Formylation of arylamines and phenols in the presence of acid to give aldehydes (Duff reaction) generally gives low yields: J. Chem. Soc., 547 (1941); Org. Synth. Coll., 4, 866 (1963). In TFA, formylation of aromatic hydrocarbons occurs in good yield with para-selectivity: J. Org. Chem., 37, 3972 (1972). Careful control of reaction conditions enables 4-substituted phenols in TFA to be converted to either 2-formyl or 2,6-diformyl derivatives: Synthesis, 1029 (1998).

Can be used as a Mannich reagent, e.g. for the ɑ-methylenation of ketones: Synth. Commun., 26, 1775 (1996). For example with reaction scheme, see Propiophenone, A15140.
