Hydroxy-PEG1-t-butyl ester is a PEG derivative containing a hydroxyl group with a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl group can be deprotected under acidic conditions.

Thiamine is a essential nutrient required for carbohydrate metabolism; also involved in nerve function. Biosynthesized by microorganisms and plants. Dietary sources include whole grains, meat products, vegetables, milk, legumes and fruit. Also present in rice husks and yeast. Converted in vivo to Thiamine diphosphate, a coenzyme in the decarboxylation of α-keto acids. Chronic deficiency may lead to neurological impairment, bariberi, Wernicke-Korsakoff syndrome.

Sorbitol, L- is a sugar alcohol with a sweet taste which the human body metabolizes slowly. It can be obtained by reduction of glucose, which changes the aldehyde group to a hydroxyl group. Most sorbitol is made from corn syrup, but it is also found in nature, for example in apples, pears, peaches, and prunes. It is converted to fructose by sorbitol-6-phosphate 2-dehydrogenase. Sorbitol is an isomer of mannitol, another sugar alcohol; the two differ only in the orientation of the hydroxyl group on carbon 2. While similar, the two sugar alcohols have very different sources in nature, melting points, and uses.

Thiamine, named as the "thio-vitamine" ("sulfur-containing vitamin"), is a vitamin of the B complex. Thiamine is found in a wide variety of foods at low concentrations. Yeast, yeast extract, and pork are the most highly concentrated sources of thiamine. In general, cereal grains are the most important dietary sources of thiamine, by virtue of their ubiquity. Thiamine hydrochloride (Betaxin) is a (when by itself) white, crystalline hygroscopic food-additive used to add a brothy/meaty flavor to gravies or soups. It is a natural intermediary resulting from a thiamine-HCl reaction, which precedes hydrolysis and phosphorylation, before it is finally employed (in the form of TPP) in a number of enzymatic amino, fatty acid, and carbohydrate reactions.

Methotrexate 5-methyl ester is an impurity of Methotrexate, a folic acid antagonist. Used as a antineoplastic and antirheumatic.

THP-PEG8-Tos is a PEG linker. The PEG linker contains 7 units of ethylene glycol.

Tralomethrin is an agricultural chemical used as a pyrethroid insecticide. It kills by modifying the gating kinetics of the sodium channels in neurons, increasing the length of time the channel remains open after a stimulus, thereby depolarizing the neuron for a longer period of time. This leads to uncontrolled spasms, paralysis, and eventual death.

Irganox 1010 is an antioxidant.

Micronomicin sulfate is an aminoglycoside antibiotic originally isolated from Micromonospora. It is active against S. aureus, B. subtilis, B. cereus, E. coli, and K. pneumoniae.

MDK-4025 is an inhibitor of the high voltage-activated (HVA) Ca2+ current in pyramidal neurons. The last four digits of the compound's CAS registry number are used in its name.

MeBIO is a negative control analog of BIO, and an aryl hydrocarbon receptor (AhR) agonist. It causes redistribution of AhR to the nucleus.

m-PEG3-acid chloride is a PEG derivative containing a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media.

Agaricic acid is an adenine nucleotide translocase antagonist.

Alfrutamide is a phenolic amide that has diverse biological activities including anti-inflammatory, antioxidative, and antiproliferative properties. It decreases nitric oxide (NO) production and inducible NO synthase (iNOS) activity and increases NO scavenging without inducing cytotoxicity. It also scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH) radicals in TLC autographic and spectrophotometric assays.

Biotin Hydrazide, or Biotin-Hz, is a carbohydrate reactive biotinylation reagent. Biotin Hydrazide is a great choice for labeling mouse monoclonal antibodies, lectins, sugars, unpaired cytosine residues in nucleic acids, and glycoprotiens.

Cefadroxil, also known as Duricef, is an antibiotic effective against pyodermic skin diseases, such as Staphylococcus aureus and Streptococcus pyogenes.

Alendronic acid is a nonhormonal medication for the treatment of postmenopausal osteoporosis in women. This drug builds healthy bone, restoring some of the bone loss as a result of osteoporosis.

Ranitidine is a non-imidazole blocker of those histamine receptors that mediate gastric secretion (H2 receptors). It is used to treat gastrointestinal ulcers. It is commonly used in treatment of peptic ulcer disease, gastroesophageal reflux disease, and Zollinger–Ellison syndrome.

Desacetylcefotaxime also known as 3-Desacetyl cefotaxime, is an impurity of cefotaxime sodium salt (sc-202989), a broad-spectrum cephalosporin antibiotic.

NSC-57969 is a MDR-selective agent, exhibiting a robust Pgp-dependent toxic activity across diverse cancer cell lines.

Biotin-PEG4-amine is a PEG derivative containing a biotin group and a terminal primary amine group. The amine group can be coupled to carboxyl groups or 5'phosphate groups to form stable amide bonds. The hydrophilic PEG spacer increases solubility in aqueous media and increases membrane impermeability of the molecules conjugated to the biotin compound. It also helps to minimize steric hindrance involved with the binding to avidin molecules. Therefore, PEG Linkers can be useful in the development of antibody drug conjugates and drug delivery methods.

2-Allyl-p-cresol is a biochemical.

Pivalanilide is a biochemical.

Acetylcholine bromide has nociceptive action.

Esfenvalerate is a common insecticide.

Cyromazine is a pesticide.

3-Hydroxyterphenyllin is a p-terphenyl fungal metabolite with antioxidant, antiproliferative, antibacterial, and antiviral properties. 2 3-Hydroxyterphenyllin inhibits the growth of HeLa cervical, A549 lung, and HepG2 liver cancer cells as well as methicillin-resistant S. aureus (MRSA) and V. vulnificus bacteria. It also inhibits HIV-1 integrase in both coupled and strand transfer assays.

Methotrexate 1-methyl ester is an impurity of Methotrexate, a folic acid antagonist. Used as a antineoplastic and antirheumatic.

Mal-PEG2-amine TFA salt is a PEG derivative containing a maleimide group and an amine group. The hydrophilic PEG spacer increases solubility in aqueous media. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol.
