Toxicology of Ietraethylene Glycol Di-N-Heptanoate
Drug and Chemical Toxicology, 1985Tetraethylene Glycol-Di-N-Heptanoate (TEGDH), a chemical added to polymers to improve flexibility, has a very low acute toxicity following both oral administration and inhalation in rats. The oral LD50 is 25 g/kg in females and greater than 25 g/kg in males. Its approximate lethal concentration for a 4-hr.

11,12-Secoprostaglandins. 4. 7-(N-Alkylmethanesulfonamido)heptanoic acids
Journal of Medicinal Chemistry, 1977A series of 7-(N-alkylmethanesulfonamido) heptanoic acids has been prepared which represents an extension of our 8-aza-11,12-secoprostaglandin studies. The studies. The compounds mimic the natural prostaglandins in that they markedly stimulate cAMP formation in the mouse ovary assay.

Evaluation of 4-methylumbelliferyl heptanoate as a substrate for oat lipase
Journal of Cereal Science, 1989The fluorogenic substrate 4-methylumbelliferyl heptanoate (MUH) has been reported to be suitable for measurement of lipase activity in cereal grains. In the present study, MUH hydrolysis was compared with a conventional lipase assay which measured the release of free fatty acids (FFA) from endogenous substrates in oats.

Corrosion inhibitors based on chitosan-heptanoate modified beidellite
Applied Clay Science, 2012Abstract This study deals with the development of a novel inhibitor based on heptanoate anions encapsulated within chitosan-modified beidellite. Included in coating, this inhibitor ensured efficient protection of metals against wet corrosion via permanent controllable release of the heptanoate inhibitor.

Extraction of Lanthanides with Mixtures of Crown Ethers and Heptanoic Acid
Solvent Extraction and Ion Exchange, 2003Abstract The liquid extraction of some lanthanides (Pr, Gd, and Yb) with mixtures of heptanoic acid H3C(CH2)5COOH (HA) and crown ethers (B) benzo‐15‐crown‐5 (B15C5), dicyclohexano‐18‐crown‐6 (DH18C6), and 18‐crown‐6 (18C6) in carbon tetrachloride (CCl4) as a solvent from aqueous chloride medium at constant ionic strength μ = 0.1 is investigated.

n‐Heptanoic acid by the caustic oxidation of 2‐octanol
Journal of the American Oil Chemists' Society, 1988Abstractn‐Heptanoic acid (97% pure) was prepared in 86% selectivity by the reaction of 2‐octanol with molten 50:50 NaOH‐KOH at 320 C using a meshing blade agitator and product heptanoic acid as an initiator.

Studies on the inhibitory effects of zinc heptanoate on microorganisms.
Giornale di batteriologia, virologia ed immunologia, 1981Inhibitory effect of zinc heptanoate was observed on different cultures of bacteria and fungi. Growth of all the bacteria was inhibited by the compound. Greatest inhibition was seen in the case of Staphylococcus albus, Streptococcus pyogenes, Shigella dysenteriae, Shigella sonnei, Shigella flexneri, Salmonella typhi, S. paratyphi A, S.
