Nature: chena crystalline poda kana crystalline. 115-118 ° C kunyunguduka, nzvimbo yekubikira, 297-298 ° C. Soluble mu ethanol, ethyl ether uye acetone, micro-soluble mumvura, chloroform, carbon disulfide uye petroleum ether. Kunhuhwirira kwakakosha uye kuravira, kunhuhwirira zvishoma, Zhuo Ma.
Kugadzirira: p-hydroxybenzoic acid uye ethanol pamberi pe sulfuric acid catalyst for esterification, esterification mumvura mushure mekupedzwa kwecrystallization, zvino kuburikidza nesefa, mune pickling zvigadzirwa.: organic intermediates. For Preservatives, antimicrobial agent, inoshandiswa mukudya, cosmetics nemishonga. Inoshandiswawo kuongorora organic reagents. Izvo zvinhu zviri paforoma, mbiriso uye mabhakitiriya ane yakakura antibacterial mhedzisiro, mbiriso uye mold kune basa rakasimba, asi kunyanya kune bhakitiriya Gram-negative bacilli uye basa reLactobacillus murombo. Chikafu nemishonga inochengetedza kuchengetedza fungicides.
