Tulipalin A (α-methylene-γ-butyrolactone) (2-Methylenebutyrolactone) which has some phytotoxicity is a natural compound extracted from Tulipa gesneriana.

Rosin is a natural product,may have therapeutic potential for the treatment of inflammation

Diethyl fumarate, a decomposition product of the pesticide Malathion, causes nonimmune contact urticaria on the skin.

Phthalate ester used as plasticizers and additives. Used in toxicology studies as well as risk assessment studies of food contamination that occurs via migration of phthalates into foodstuffs from food-contact materials (FCM).

Cymen-ar-ol is a broad spectrum and highly effective bactericide that can contact mucous membrane.

Hexylamine is a primary aliphatic amine that presents as a flammable, water-white liquid with a strong, unpleasant ammonia-like, fishy odor. Hexylamine is used as a chemical reagent and versatile synthetic intermediate in organic synthesis, including the creation of polypeptides, functionalized materials for CO₂ capture, and lipid nanoparticles for drug delivery, Hexylamine is toxic by inhalation, ingestion, or skin contact, requiring careful handling, storage, and disposal procedures.

Cholesteryl palmitic acid is a cholesteryl ester. A cholesteryl ester is an ester of cholesterol. Fatty acid esters of cholesterol constitute about two-thirds of the cholesterol in the plasma. Cholesterol is a sterol (a combination of steroid and alcohol) and a lipid found in the cell membranes of all body tissues and transported in the blood plasma of all animals. The accumulation of cholesterol esters in the arterial intima (the innermost layer of an artery, in direct contact with the flowing blood) is a characteristic feature of atherosclerosis. Atherosclerosis is a disease affecting arterial blood vessels. It is a chronic inflammatory response in the walls of arteries, in large part to the deposition of lipoproteins (plasma proteins that carry cholesterol and triglycerides).

Shyobunone and isoshyobunone have insecticidal and repellant activity, they exhibit strong contact toxicity against Lasioderma serricorne (LS adults with LD50 values of 20.24 and 24.19 ug/adult, respectively; they are strongly repellent against Tribolium

DI-N-OCTYL PHTHALATE (Standard) is the standard substance of DI-N-OCTYL PHTHALATE, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Phthalate ester used as plasticizers and additives. Used in toxicology studies as well as risk assessment studies of food contamination that occurs via migration of phthalates into foodstuffs from food-contact materials (FCM).

Atranol is a potent sensitizer found in oakmoss extract. It causes contact dermatitis by triggering an allergic response in the immune system. Atranol holds potential for research into the causes of contact dermatitis and allergens in cosmetics.

2-epi-Abamectin, a degradation product of abamectin, exhibits toxicity towards the two-spotted spider mite in contact assays, possessing an LC50 value of 4 ppm. This indicates it is approximately 100-fold less potent than its precursor, abamectin.

Turricolol E is a prenylated phenolic compound, which can be extracted from the glandular trichomes of Turricula parryi. Prenylated phenolics are known to cause contact dermatitis.
