Trimetazidine
Product name:Trimetazidine
CAS: 5011-34-7
Molecular Formula: C14H22N2O3
Molecular Weight: 266.34
Product description:A piperazine derivatives, commodity called great force, chemical name of 1 - (2 and 4 - preparation benzyl) piperazine hydrochloride, two for the angina pectoris medicine. Against epinephrine, norepinephrine, and the effect of vasopressin, can directly relax vascular smooth muscle, reduce vascular resistance, increase the flow of blood to the coronary artery and peripheral circulation and promoting myocardial metabolism and energy production. At the same time reduce the myocardial oxygen consumption and improve myocardial oxygen supply and demand balance. Can increase the tolerance of cardiac glycoside, also can increase the exercise tolerance test of angina patients, significantly reduce angina frequency, reduce the dosage of nitroglycerin. Clinical used in the treatment of coronary artery insufficiency, angina pectoris and old myocardial infarction; For those with severe cardiac insufficiency with digitalis.

Tri-n-butylphosphine
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.

Trimebutine
Product name:Trimebutine
CAS Number: 39133-31-8
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.
