Compounds and their use in detecting an amino acid and/or latent fingerprint

The present invention relates to compounds of amino acids and/or latent fingerprints of formula:[Het]-CHOwherein Het is a nitrogen containing heterocyclic system in which a nitrogen atomis substituted by a substituted or unsubstituted alkyl group, aryl group, aralkyl group or alkaryl group, and -CHO is an aldehyde group, and salts thereof. Preferred compounds are N-methylpyridine-4-carboxaldehyde iodide, N-methyl-4-carboxaldehydequinolinium iodide, N-methyl-lH-benzimidazole-2-carboxaldehyde, N-phenyl-lH-benzimidazole-2-carboxaldehyde and N-methyl-lH-imidazole-2-carboxaldehyde. In use, the compound may react with an amino acid or latent fingerprint to produce a detectable product e.g. a chromophore or compound exhibiting fluorescence. The invention also provides: a composition comprising the compound and which may in addition comprise a carrier e.g. a polar solvent such as ethanol, methanol or a chlorofluorocarbon; a method for detecting a latent amino acid and/or fingerprint; and an apparatus for detecting a latent amino acid and/or fingerprint.
