Propyl hydroxybenzoate

A closer inspection of A. luteoviolaceus by different groups provided a further variety of highly active metabolites, tetrabromopyrrole, hexabromo-2,2 -bipyrrole, tetrabromobiphenol, several simple phenols including 4-hydroxy-benzaldehyde and n-propyl-4-hydroxybenzoate, violacein (5) and related pigments, and the extremely strong siderophore alterobactin [97].

Solid-liquid solvent-free PTC was applied, with noticeable improvement and simplification compared with classical procedures, in a green chemistry context, for synthesis of some aromatic esters useful as cosmetic ingredients - 3-methylbutyl 4-methoxycinnamate, 2-ethylhexyl 4-methoxycinnamate, 2-ethylhexyl 4-(dimethylamino)benzoate, and 2-ethylhexyl salicylate, all well-known ultraviolet B sunscreen filters, 4-isopropylben2yl salicylate, a UV absorber and cutaneous anti-lipoperoxidant, the parabens propyl 4-hydroxybenzoate and butyl 4-hydroxyben-zoate (Eq. 7), and antimicrobial agents [16].

Ethyl 4-hydroxybenzoate is a highly effective preservative with moderately good solubility in water. The spectrum of effectiveness in demonstrated by the MIC in Table 81. As a food preservative ethyl 4-hydroxybenzoate is often used in combination with propyl 4-hydroxybenzoate (8.1.11.3.) thus it is possible in most cases to use smaller overall amounts of alkyl 4-hydroxybenzoate than would otherwise be necessary. The favourable properties of ethyl 4-hydroxy benzoate makes it also highly suitable for preserving cosmetics and pharmaceuticals most frequently mixtures of alkyl 4-hydroxybenzoates are used. 

Alkali fusion of lunarine yielded spermidine, HaN(CH2)3NH(CH2)4NH2, thus accounting for all of the N atoms 159). There was also obtained a mixture of acids and phenolic products the most important of which were 2,4 -dihydroxydiphenyl-5,3 -dicarboxylic acid and 3-propyl-4-hydroxybenzoic acid. These products along with exhaustive spectral data suggest plausible structures for this alkaloid 160, 161).
