Sulfonylureas (UK: sulphonylurea) are a class of organic compounds used in agriculture.

Sulfonylureas used as herbicides.
A large number of sulfonylureas are used as herbicides. They function by interfering with biosynthesis of the amino acids valine, isoleucine, and leucine. Compounds in this class include amidosulfuron, azimsulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, ethametsulfuron-methyl, cinosulfuron, ethoxysulfuron, flazasulfuron, flupyrsulfuron-methyl-sodium, imazosulfuron, metsulfuron-methyl, nicosulfuron, oxasulfuron, primisulfuron-methyl, prosulfuron, pyrazosulfuron-ethyl, rimsulfuron, sulfometuron-methyl, sulfosulfuron, thifensulfuron-methyl, triasulfuron, tribenuron-methyl, and triflusulfuron-methyl.

Piracetam is a Nootropic that displays cognitive enhancing properties. Piracetam is a modulator of neurotransmitter-induced ion flux and is proposed to enhance neurotransmission via this modulation. Through AMPA receptors, Piracetam potentiates Na+ influx. Piracetam also facilitates the efficiency of cholinergic neurotransmission at muscarinic receptors.

Amyl nitrite is a rapidly acting vasodilator administered by inhalation. 0.3 ml is supplied in a covered thin glass capsule which is easily crushed between the fingers. Amyl nitrite is a clear, yellowish liquid having a peculiar ethereal, fruity odor. It is volatile, even at low temperatures, and is flammable. This product is stabilized with Flexol(tm) 2 percent. The structural formula of amyl nitrite is: C5H11NO2.

Amyl nitrite causes a non specific relaxation of smooth muscle with the most prominent actions occurring in vascular smooth muscle. This effect on vascular smooth muscle results in coronary vasodilation and decreased systemic vascular resistance and left ventricular preload and afterload. Myocardial ischemia is relieved in patients with angina pectoris, with an abatement of chest pain and possibly other related symptons. Amyl nitrite vapors are absorbed rapidly through the pulmonary alveoli, manifesting therapeutic effects within one minute after inhalation. The drug is metabolized rapidly, probably by hydrolytic denitration; approximately one-third of the inhaled amyl nitrite is excreted in the urine.
Amyl nitrite is indicated for the rapid relief of angina pectoris. Its effect appears within 30 seconds and lasts for approximately 3 to 5 minutes.

Since it may increase intraocular and intracranial pressures, amyl nitrite is contraindicated or should be used with great caution in patients with glauc
oma, recent head trauma or cerebral hemorrhage. Amyl nitrite can cause harm to the fetus when it is administered to a pregnant woman because it significantly reduces systemic blood pressure and blood flow on the maternal side of the placenta.

A drug that has anti-inflammatory, antipyretic, and analgesic.

Siman Ltd. Is able to offer to its customers a diverse range of industrial chemicals that finds an application in: leather, textile and rubber industry, heat treatments of metals and others.

The products that we offer are:

Chromium trioxide (Chromic acid) - it is a strong acid and oxidizing substance. When neutralized with alkali forms dichromate or chromium compounds. The low sodium content is appropriate for processes of catalyst and other special application.
Chromic oxide (Dichromium trioxide), metallurgical is an inorganic compound. Light green crystalline powder, soluble in water and organic solvents and used in metallurgy as a pigment.
Potassium nitrate, technical grade is a crystalline powder with white colour, sometimes slightly yellowish-green. It is easy soluble in water. Used in many sectors in industry and agriculture: as a component of some types of powders and pyrotechnics mixtures; in the glass industry for decolorization and clarification of crystal glass to reinforce the glass; in the manufacture of enamels, thermal salts; in the metallurgy for hardening/tempering of metals; as an undiluted valuable fertilizer containing two nutrients.
Sodium nitrate is a white solid substance which is very soluble in water. It is used in the chemical glass, metallurgical and other industry; in the manufacturing of pipes, as well as fertilizer.
Sodium fluoride. Sodium fluoride is white crystalline solid. Used in the brewing industry and in the distillation of the spirits; as a substitute of HF in stainless steel pickling; in the manufacture of casein glue and other adhesives; in glass polishing; in fluoridation of drinking water; enamels and ceramics, toothpastes; salts
Caustic soda (Sodium hydroxide). Strong base, very soluble in water, alcohol, glycerin and absorbs carbon dioxide and moisture from the air. The main use of Sodium hydroxide is as a chemical and in the manufacturing of other chemicals. It is used also in textile industry as well as in making paper and cellulose.

Siman Ltd. Has extensive experience in metal finishing. Galvanotechnics is an area of applied electrochemistry that deals with the processes of deposition of metal coating on the surface of the metal and non-metal products by leakage of electrical current through a solution of their salts. Our product and accessories are guaranteed quality and are used in all types of plating operations such as chrome, nickel, cadmium, silver and copper coating and etc.

The range of our products includes:

Chromium trioxide. Chromic acid is a strong acid and oxidizing agent. When neutralized with alkalis, chromic acid forms dichromate or chromate compounds. The low sodium content is suitable for use in catalysts and other special applications.;

Ferrous sulfate monohydrate is a common fertilizer additive as a supplement of Fe and a booster for the absorption of N, P elements to plants. When used as base fertilizer for soil, it can help to prevent diseases like flower chlorotic disorder; when used as foliar fertilizer with its solution, it can help to defense insect pests or diseases such as dactylieae, chlorosis, cotton anthracnose, etc. Adding ferrous sulfate in feed can effectively prevent illnesses such as iron-deficiency anemia,iron-deficiency lassitude, abnormal body temperature, etc. It can also increase survival rate of livestock, improve its growth and development, strengthen its disease resistance. Meanwhile, ferrous sulfate can be used in water treatment, iron salts production, mordant, preservative and other industries.

MnSO4 is one of the most important micro-nutrients fertilizer, which can be used for base fertilizer, seed-presoaking, seed-dressing and foliage-spraying to promote crops growth, increase yields and engage in the synthesis of chlorophyll. In animal husbandry and feed industry, it is used as a feed additive to promote animal growth and fatten the livestock. Apart from agricultural applications, MnSO4 can also be the raw materials to electrolyze Mn or produce other manganese salts, or be used in other industries like paper-marking, ceramic, dyeing, mineral separation, etc.
