Product name:Tri-n-butylphosphine
CAS: 998-40-3
Molecular Formula: C12H27P
Molecular Weight: 202.3165
Product description:And the most commonly used three different ligand phosphorus reagents, tributyl phosphine is a nucleophilic reagent. It is a relatively weak alkali (pKa in MeNO3 = 8.70; in methanol pKa = 5.60), using solvent without strict oxygen, but need to use inert gas protection, if exposed to the air can produce severe oxidation reaction, generate oxygen tributyl phosphine and dibutyl phosphite phosphonic acid butyl ester. Sulfide and sulphur ester synthesis tributyl phosphine and disulfide and alcohol reaction can generate corresponding sulfide and Bu3PO; And disulfide and carboxyl reaction can get sulphur ester (type 1) [1]. Catalytic addition reaction of carbonyl and alkene Because of tributyl phosphine with nucleophilic attack after double bond can lead to migration, electron cloud addition reaction to occur.

Molecular Weight: 387.47
Molecular Formula: C22H29NO5
Solubility: Soluble in water (
Application: An opioid receptor agonist
Storage: Store at 4° C
Product description:
Trimebutine is a drug with antimuscarinic and weak mu opioid agonist effects. The maleic acid salt of trimebutine is marketed under the trademark of Debridat, Recutin, Polybutin, or Modulon for treatment of irritable bowel syndrome and other gastrointestinal disorders. The major product from drug metabolism of trimebutine in human beings is nor-trimebutine, which comes from removal of one of the methyl groups attached to nitrogen. Both Trimebutine and its metabolite are commercially available.

Trimanganese tetraoxide
Product name:Trimanganese tetraoxide
CAS: 1317-35-7
Molecular Formula: Mn3O4
Molecular Weight: 228.82
Product description:Stable at room temperature under normal pressure. Palm red or brown crystalline powder, after burning into crystallization, is a kind of structure of spinel as Mn (Mn) 2 m1, Mn and Mn ions distributed on the two different lattice position.Mainly used in electronic industry, the production of soft magnetic ferrite materials. Soft magnetic ferrite is composed of manganese, zinc, iron oxide in a certain proportion of mixed sintering molding manufacture, has a narrow remanence curve, can be magnetized repeatedly, at the same time, the dc resistance rate is very high, can avoid the eddy current loss. Can be used as the electronic computer in the core, disk and tape storage information, telephone transformer and inductor, high quality TV flyback transformers, magnetic recording head, inductors, magnetic amplifier, saturated inductor, antenna rod, etc. Also can be used for some of the paint or coating, spray paint or coating containing four oxidation three manganese than on steel containing titanium dioxide or paint or coating containing iron oxide has better corrosion resistance.

Triflusal
Product name:Triflusal
CAS: 322-79-2
Molecular Formula: C10H7F3O4
Molecular Weight: 248.16
Product description:The drug by the irreversible inhibition of the platelet epoxy synthase is reduce the biological form thrombus, its main metabolites HTB (3 - hydroxy - 4-3 acid) is an enzyme called cyclooxygenase platelet reversible inhibitor, and its half-life is very long (about 34 hours), it is advantageous to the willow three fluorine antiplatelet activity; HTB and metabolites can inhibit platelet phosphodiesterase increased platelet inside the cAMP, the content, resulting in platelet aggregation. Against the role of endothelial cell ring oxidase minimal, does not affect the synthesis of prostaglandins, and its metabolites can increase the platelet coagulation effect, the drug used in the human body does not increase the bleeding time, clinical trials to confirm if the thrombolysis therapy used at the same time, also do not increase the incidence of cardiovascular hemorrhage, the unstable angina pectoris, coronary artery molding and short circuit, the procedure for acute myocardial infarction (mi), the validity of thromboembolic disease and peripheral vascular disease and aspirin are the same, but very little bleeding complications, used for cerebrovascular disease secondary beforehand

Triflupromazine
Product name:Triflupromazine
CAS: 146-54-3
Molecular Formula: C18H19F3N2S
Molecular Weight: 352.45
Product description:This drug is chlorpromazine antipsychotic effect is strong. Used in the treatment of schizophrenia. Also used in sickness. After taking antipsychotic effect of normal treatment quantity, quiet, decreased activity, emotional indifference, decline of attention, are not interested in things around, when quiet, can induce sleep, but easily awakened. Mental patients, without excessive suppression, quickly control the manic symptoms of schizophrenia patients, reduce or eliminate hallucinations, delusions, lead to the normal activity of thinking and behavior. Now think of chlorpromazine antipsychotic effect is mainly due to the blocking the limbic system associated with emotional thinking of dopamine receptors. Uplink activation system and blocking the mesh structure of alpha adrenaline receptors, are associated with calm stability.
