Trimethyl phosphate (Standard) is the analytical standard of Trimethyl phosphate (HY-A0108A). This product is intended for research and analytical applications. Trimethyl phosphate is a methylating agent. Trimethyl phosphate transfers methyl groups to aliphatic alcohols, phenols, and amines.

Thiothixene is a typical antipsychotic. It selectively binds to dopamine D2 over D1, D3, and D4 receptors (Kis=0.417, 338, 186.2, and 363.1 nM, respectively). Thiothixene also binds to various serotonin (5-HT), histamine H1, α1- and α2-adrenergic, muscarinic acetylcholine, and sigma receptors (Kis=15-5,754 nM) as well as the dopamine, norepinephrine, and serotonin transporters (Kis=3.16-30 μM). In vivo, thiothixene reduces spontaneous and amphetamine-induced locomotor activity in rats. It enhances latent inhibition, as measured by a decreased lick latency in response to light and foot shock stimuli, which is a measure of selective attention in rats.3 Thiothixene also increases competitive behavior in submissive mice, indicating antidepressant-like behavior.

Hydroxystilbamidine diisethionate, a dye capable of binding to both DNA and RNA, is a powerful inhibitor of cellular ribonucleases. Hydroxystilbamidine diisethionate is a retrograde fluorescent tracer and histochemical stain.

Niacinamide ascorbate is a micronutrient with radioprotective properties. Niacinamide ascorbate works as an antioxidant along with vitamin C, vitamin E and other compounds to mitigate the risks associated with exposure to ionizing radiation. Niacinamide ascorbate helps reduce the likelihood of radiation-induced diseases such as acute leukemia, breast cancer, thyroid cancer and mutations, thereby protecting the human body from the harmful effects of radiation.

Guanidine-¹³C,¹⁵N₃ hydrochloride (Guanidinium-¹³C,¹⁵N₃ (chloride)) is the ¹⁵N, ¹³C-labeled Guanidine hydrochloride (HY-B0178A). Guanidine hydrochloride is a strong protein denaturant. Guanidine hydrochloride causes proteins to assume a random coil conformation.

Azathioprine-d₃ (BW 57-322-d₃) is the deuterium labeled Azathioprine (HY-B0256). Azathioprine (BW 57-322) is an orally active immunosuppressive agent. Azathioprine can be converted in vivo to the active metabolite 6-mercaptopurine (6-MP). Azathioprine has myelosuppressive effects and induces apoptosis.

Guaifenesin-d₅ cyclic carbonate is the deuterium labeled Guaifenesin cyclic carbonate.
