Phenylmercuric ammonium acetate is a fungicide and bactericide. It is used for the seed treatment.

Cacodylic acid also known as dimethylarsinic acid (DMA) has been used as a herbicide. As a part of agent blue it used to destroy broadleaf plants and trees, especially rice paddies during the Vietnam War. DMA is the major metabolite formed after exposure to tri- (arsenite) or pentavalent (arsenate) inorganic arsenic (iAs) via ingestion or inhalation in both humans and rodents. DMA induces an organ-specific lesion--single strand breaks in DNA. Mechanistic studies have suggested that this damage is due mainly to the peroxyl radical of DMA and production of active oxygen species by pulmonary tissues. Multi-organ initiation-promotion studies have demonstrated that DMA acts as a promotor of urinary bladder, kidney, liver and thyroid gland cancers in rats and as a promotor of lung tumors in mice. Thus it was shown, that DMA played a role in the carcinogenesis of inorganic arsenic.

Butacaine is a local anesthetic. It should not be used with people who have a history of allergies due to the possibility of anaphylactic shock.

Disodium Cupric Citrate is citric acid salt with marked antioxidant activity. Disodium Cupric Citrate is one of the various forms in which the micronutrient copper is supplied in a fertiliser. Cupric supplementation at pharmacological doses beyond the recommendations of National Research Council has been widely applied in the feed industry to improve pig performance. Dietary Cupric Citrate supplementation enhanced growth performance in weaned pigs.

Phenacaine (UNII: V3M4D317W8) also known as holocaine is a local anesthetic used in ophthalmic medicine. Like other local anesthetics it inhibits the specific calmodulin-dependent stimulation of erythrocyte Ca2+-ATPase (ATP phosphohydrolase) and cyclic nucleotide phosphodiesterases (3',5'-cyclic-nucleotide 5'-nucleotidohydrolase) from brain and heart. Basal activities of these enzymes in the absence of calmodulin are relatively unaffected by concentrations of local anesthetics that strongly inhibit the specific stimulation by calmodulin. Increasing calmodulin, but not Ca2+, overcomes the inhibitory action of the local anesthetics on brain phosphodiesterase. However, excess calmodulin does not fully restore activity of erythrocyte CA2+-stimulated ATPase. Although the mechanism(s) by which the local anesthetics act is unclear, they inhibit binding of 125I-labeled calmodulin to the erythrocyte membrane. Antagonism of calmodulin provides a molecular mechanism that may explain the inhibition of many Ca2+-dependent cellular processes by local anesthetics--e.g., Ca2+ transport, exocytosis, excitation-contraction coupling, non-muscle-cell motility, and aggregation. Phenacaine hydrochloride is registered by FDA as an anorectal drug product and is in the list of OTC active ingredients. The Ointment Ophthalmic Holocaine and Epinephrine (1.5% phenacaine hydrochloride) were distributed by National Drug Co., a corporation, Philadelphia, Pa. and in 1939 and was alleged to be misbranded since it contained less phenacaine hydrochloride than indicated by the labeling.

Acetanilide is a synthetic organic compound introduced clinically in 1886 as a fever-reducing drug. Its effectiveness in relieving pain was discovered soon thereafter and it was used as an alternative to aspirin for many years in treating such common complaints as headaches, menstrual cramps, and rheumatism. Unfortunately, Acetanilide exhibited an unacceptable profile of toxic effects, the most alarming being cyanosis due to methemoglobinemia. The toxic profile prompted the search for supposedly less toxic aniline derivatives such as phenacetin. After several conflicting results over the ensuing fifty years, it was established in 1948 that acetanilide was mostly metabolized to paracetamol (USAN: acetaminophen) in the human body and that it was the paracetamol that was responsible for the analgesic and antipyretic properties. Paracetamol has since replaced acetanilide usage because it is less likely to induce blood disorders. The observed methemoglobinemia after acetanilide administration was ascribed to the small proportion of acetanilide that is hydrolyzed to aniline in the body. Acetanilide is no longer used as a drug in its own right, although its primary metabolite, paracetamol, has been widely succesful.

Tolindate, a thiocarbamate, is a synthetic antifungal approved by FDA as an over-the-counter (OTC) drug product and is marketed by Norcliff Thayer Inc. It was prepared by treating 5-indanyl thionochloroformate with N-methyl-m-toluidine and patented in 1970 by USV Pharmaceutical Corporation tas a compound with strong topical antifungal activity that may be administered topically in the form of ointments and solutions. It was used in eastern Europe as Dalnate (USV Pharmaceutical Corporation trademark registerd in 6/26/1973) for topical application in the treatment of various dermatoses. Produced by ZORKA Pharma (at present Hemofarm a.d., Serbia) topical cream or solution Dalnate was registered for marketing in Russia.

Antimicrobial agent Fluorosalan is classified as Category II for use as antiseptic handwash, healthcare personnel handwash, patient preoperative skin preoperative skin preparation, and surgical hand scrub products. In the 1994 TFM (59 FR 31402 at 31435-31436), FDA proposed that the active ingredient fluorosalan be found not GRAS/GRAE for the uses referred to in the 1994 TFM as antiseptic hand wash and health care personnel hand wash.

Sodium 3,4-dimethylphenylglyoxylate is a topical analgesic, sunscreen ingredient, UV-B absorber, FDA approved.

p-Chloromercuriphenol is used as intermediate in organic synthesis. Can cause allergic reaction.
