2-Iminothiolane HCl (Trauts reagent) is a useful RNA-protein crosslinking reagent and an effective thiolation reagent for the introduction of sulphydryl groups into oligosaccharides.

Dimethyl sulfoxide (DMSO) is a commonly used solvent to dissolve polar and non-polar compounds. Dimethyl sulfoxide has been widely used for masterbatch preparation of compounds in biological experiments. Dimethyl sulfoxide has bacteriostatic activity.

Lipopolysaccharides (LPS), derived from Escherichia coli O55:B5, are essential components of the outer membrane of Gram-negative bacteria. Composed of lipid A, a core oligosaccharide, and an O-specific polysaccharide, LPS exhibits strong immunogenicity. It activates immune cells via the TLR4 receptor, induces chemotactic cell migration and cytokine secretion, and helps maintain the integrity of the bacterial outer membrane, protecting against bile salts and lipid-based antibiotics. LPS is commonly used to establish inflammatory models, including arthritis, chronic obstructive pulmonary disease (COPD), acute respiratory distress syndrome (ARDS), and gastrointestinal disease models.

SBE-β-CD (Sulfobutylether-β-Cyclodextrin) is a β-cyclodextrin derivative with a sodium sulfonate salt separated from the lipophilic cavity by a butyl ether spacer group, or sulfobutylether. SBE-β-CD is widely used as a co-solvent in biological experiments.

D-Lin-MC3-DMA, an ionizable cationic lipid, serves as a potent siRNA delivery vehicle.

SM-102 is the only ionizable amino cationic lipid currently clinically approved for RNA therapeutics and can be used to synthesize lipid nanoparticles (LNPs). It shows potential in the development of LNPs for the delivery of mRNA-based vaccines.

Pullulan is a water-soluble extracellular polysaccharide derived from Aureobasidium pullulans, a linear, unbranched natural polymer with a high concentration of hydroxyl groups and oral activity. It features a unique chain pattern of two α-(1→4) and one α-(1→6) glycosidic bonds in its maltose repeat units, and is widely used in biomedical and biochemical experiments.

Citric acid trilithium salt tetrahydrate (Lithium citrate tribasic tetrahydrate) , the active component of Lithium, is a medicine used in the therapy of psychiatric disease. It has shown the effects of signaling pathways and metabolic in the brain based on the particular disease and clinical condition model. According to the reports, Citric acid trilithium salt tetrahydrate was used as a mood stabilizer when treating bipolar mood disorders (BD) and lower the risk of self-harm in BD patient. In addition,Citric acid trilithium salt tetrahydrate has been the choice drug in the therapy of acute manic episodes.Citric acid trilithium salt tetrahydrate also could dissolve uric acid crystals in urine achieved from patients with gout. Besides,Citric acid trilithium salt tetrahydrate have some dose-dependent side-effects. The the main side-effects of Lithium Citrate is the tendency to inhibit the prostatic acid phosphatase enzyme (PAP), which result in the accumulation of PAP.

D-Sorbitol (Sorbitol) is a polyhydric alcohol with about half the sweetness of sucrose, occurring naturally and also produced synthetically from glucose. Formerly used as a diuretic, it may still be used as a laxative and in irrigating solutions for certain surgical procedures. It is also utilized in various manufacturing processes, as a pharmaceutical aid, and in several research applications.

Gluconate Calcium (Gluconic acid hemicalcium salt) is the calcium salt of gluconic acid, used as a calcium replenisher in hypocalcemic states.

Maltose (maltobiose) is a reducing sugar and is a disaccharide formed from two units of glucose bound by a (1-4) bond. Maltose can be used as an energy source for bacteria.

Diphenylacetonitrile (Dipan) is used as herbicide and industrial intermediate.

Decamethonium bromide (Syncurine) is a neuromuscular blocker and nicotinic AChR partial agonist.

L-Glutathione reduced (Glutathione) is a naturally occurring tripeptide found in cells as an endogenous antioxidant that scavenges oxygen free radicals. L-Glutathione reduced is a cofactor for certain enzymes and is involved in the rearrangement of protein disulfide bonds and the reduction of peroxides.

Tryptamine hydrochloride is a monoamine alkaloid, metabolite of tryptophan and CNS active substance, agonist of 5-HT4 receptor, TAAR1 and AHR, with potential for blood-brain barrier permeability.

Sodium citrate dihydrate (Trisodium citrate dihydrate) is an anticoagulant, and also used as a buffer and food preservatives.

Glycol chitosan, a chitosan derivative with hydrophilic ethylene glycol branches, inhibits E. coli, S. aureus, and S. enteritidis growth (MICs: 4 μg/mL, 32 μg/mL, and <0.5 μg/mL), and enhances membrane permeability and leakage in Glycine max [Harosoy 63W] cells.

Hexadimethrine bromide (1,5-Dimethyl-1,5-diazaundecamethylene polymethobromide) is a synthetic polymer which agglutinates red blood cells, and used as a heparin antagonist.

DL-Panthenol (DL-Pantothenyl alcohol) is the alcohol analog of pantothenic acid (vitamin B5) and is thus a provitamin of B5. In organisms, it is quickly oxidized to pantothenate.

Caprylic/Capric Triglyceride, a compound consisting of triglycerides and esters derived from fractionated vegetable oil, and fatty acids from coconut and palm kernel oils, serves as a food additive and is utilized in cosmetics. This substance demonstrates outstanding oxidation stability.

DTNB (Ellman's Reagent) is used to quantify thiol groups in a sample and measure low-molecular-mass thiols, such as glutathione, in pure solutions and biological samples [such as blood].

Enbucrilate (Butyl cyanoacrylate) is a cyanoacrylate ester utilized as a surgical tissue adhesive, which forms polymer films at oil-water interfaces, displaying varied film morphologies.

N-Succinimidyl-S-acetylthioacetate (SATA) is a protein modification agent that introduces thiol-groups into protein molecules and adds sulfhydryl groups in a protected form to proteins and other amine-containing molecules for later reaction with sulfhydryl reactive crosslinkers such as Sulfo-SMCC, Sulfo-MBS, etc.
