Hexamethylenetetramine · Urotropin · Methenamine Silver
Hexamethylenetetramine or methenamine is a heterocyclic organic compound with the formula (CH2)6N4. This white crystalline compound is highly soluble in water and polar organic solvents. It has a cage-like structure similar to adamantane.
Tarichatoxin · Tetradotoxin · Fugu Toxin
Tetrodotoxin (TTX) is a potent neurotoxin. Its name derives from Tetraodontiformes, an order that includes pufferfish, porcupinefish, ocean sunfish, and triggerfish; several of these species carry the toxin. Although tetrodotoxin was discovered in these fish and found in several other aquatic animals (e.g., in blue-ringed octopuses, rough-skinned newts, and moon snails), it is actually produced by certain infecting or symbiotic bacteria like Pseudoalteromonas, Pseudomonas, and Vibrio as well as other species found in the animals.
Diphosphorus pentoxide (1314-56-3, 72906-42-4, 16752-60-6)
Phosphorus pentoxide is a chemical compound with molecular formula P4O10 (with its common name derived from its empirical formula, P2O5). This white crystalline solid is the anhydride of phosphoric acid. It is a powerful desiccant and dehydrating agent.
Tetramethylenedisulfotetramine (TETS) is an organic compound that is used as a rodenticide (rat poison). It is an odorless, tasteless white powder that is slightly soluble in water, DMSO and acetone, and insoluble in methanol and ethanol. TETS is a sulfamide derivative, it can be synthesized by reacting sulfamide with formaldehyde under acidic condition.
1,3,4,6,7,8-hexahydro-2H-pyrimido(1,2-a)pyrimidine · hppH cpd
Triazabicyclodecene (1,5,7-Triazabicyclo[4.4.0]dec-5-ene or TBD) is a commercially available bicyclic strong guanidine base (pKa = 25.98 in CH3CN and pKa = 21.00 in THF). TBD is an organic soluble base which has been used effectively for a variety of base-mediated organic transformations such as: Michael reactions, Henry (nitroaldol reactions), Wittig reactions, Horner–Wadsworth–Emmons reactions, transesterification reactions, etherifications, ring-opening polymerizations (Scheme 1), tautomerizations and epimerizations P–C and P–N bond formations, Knoevenagel condensations, deprotonation reactions of phenols, carboxylic acids and C-acids (Scheme 2), aminolysis of esters. It is also known in deprotonated form (at the 7-position), often as a ligand, for instance in Ditungsten tetra(hpp)
Diketene is an organic compound with the molecular formula C4H4O2, and which is sometimes written as (CH2CO)2. It is formed by dimerization of ketene, H2C=C=O (IUPAC name: ethenone). Diketene is a member of the oxetane family.
