Urocanic acid (4-Imidazoleacrylic acid), synthesized in the epidermis, functions as a primary absorber of ultraviolet (UV) radiation in mammalian skin.

Imidazoleacetic acid hydrochloride (I4AA) is an imidazole derivative with potential antituberculosis properties. It also used in the preparation of acyl guanidine inhibitors of β-secretase.

Pyraclostrobin (Standard) is the analytical standard of Pyraclostrobin, primarily used for biochemical research and quantitative analysis. Pyraclostrobin is a potent, broad-spectrum fungicide. It exerts its biological effects by activating the AMPK/mTOR signaling pathway, which leads to the induction of oxidative DNA damage, mitochondrial dysfunction, and autophagy.

Imidazol-1-yl-acetic acid is a natural product that inhibits Sodium- and chloride-dependent betaine transporter and is applicable to life science research.

Thiamine hydrochloride (Standard) is the analytical standard of Thiamine hydrochloride, primarily used for quantitative analysis and metabolic research. Thiamine hydrochloride (Vitamin B1 hydrochloride) is an essential micronutrient that serves as a vital cofactor for several central metabolic enzymes, including pyruvate dehydrogenase, α-ketoglutarate dehydrogenase, and transketolase. In vivo, it is phosphorylated into its active form, Thiamine Pyrophosphate (TPP), which is directly involved in carbohydrate metabolism, the TCA cycle, and the pentose phosphate pathway. It is indispensable for cellular energy production and the maintenance of nervous system integrity.

Imidazoleacetic acid (Imidazolyl-4-acetic acid) is a blood-brain barrier-permeable full agonist of the GABAA receptor. Imidazoleacetic acid is generated through histamine oxidation in the mouse brain and exerts multiple neurochemical and behavioral effects. Imidazoleacetic acid induces centrally mediated responses including analgesia, sedation, hypnosis, and reductions in blood pressure, body temperature, isolation-induced aggression, and motor activity. Imidazoleacetic acid is valuable for neuropharmacology and neurotransmitter signaling investigations involving histaminergic and GABAergic pathways.

Mebendazole (Standard) is a reference standard of mebendazole, suitable for quantitative analysis, quality control, and biochemical studies. Mebendazole is a broad-spectrum anthelmintic agent that exerts its biological activity by disrupting microtubule polymerization. Mebendazole has shown inhibitory effects on glioblastoma multiforme in vitro and in animal models, potentially involving modulation of the Hedgehog signaling pathway. In addition, Mebendazole exhibits a certain degree of blood–brain barrier permeability.

L-Histidine (Standard) is the standard of L-Histidine (T2A2532), suitable for research related to quantitative analysis, quality control, and biochemical experiments. L-Histidine (L-(-)-Histidine) is an essential amino acid involved in protein synthesis in vivo and serves as a precursor for bioactive molecules like histamine, playing important roles in immune response and neural regulation. L-Histidine is an inhibitor of mitochondrial glutamine transport.

Fluconazole (Standard) is the standard substance of Fluconazole, and it is applicable for quantitative analysis, quality control, and related research in biochemical experiments. Fluconazole is a triazole antifungal agent that is used to treat oropharyngeal candidiasis and cryptococcal meningitis in AIDS.
