At atmospheric pressure, ammonia is a colorless gas with a characteristic pungent odor, which is extremely irritating to the eyes and upper respiratory tract. It is approximately half as dense as air and thus rises readily. With pressurization, 13 cubic feet of ammonia vapor can be condensed into 1 cubic foot. Ammonia is a common chemical of production, holding a third place in world production (Makarovsky et al., 2008). The large-scale use of ammonia is facilitated by large-scale storage
Urea is a powerful protein denaturant via both direct and indirect mechanisms. A potent emollient and keratolytic agent. Used as a diuretic agent. Blood urea nitrogen (BUN) has been utilized to evaluate renal function[3]. Widely used in fertilizers as a source of nitrogen and is an important raw material for the chemical industry.
Dimethyl adipate (DMA) is a colorless and flammable liquid. It is soluble in alcohol and ether, but sparingly soluble in water. It reacts with acids, alkalis, and strong oxidants. Dimethyl adipate is synthesized by the esterifi cation of adipic acid. Dimethyl adipate is part of a dibasic ester (DBE) blend used as a major ingredient in several paint strippers; the DBE blends used in paint stripping formulations contain a major portion (about 90%) of DMA. Dimethyl adipate is used as a chemical in
Poloxamer 407 is a nonionic surfactant that is 100% active and relatively non-toxic to cells at low concentrations, and frequently used with dye AM esters such as Indo-1 AM, Fura-2 AM, Calcein AM, Fluo-3 AM, Fluo-4 AM, Quest Fluo-8™ AM and Quest Rhod-4™ AM, etc. to improve their water solubility.
colourless liquid Dichloropropane is a colorless stable liquid. Sweet, chloroform-like odor. The odor threshold in air is 0.25 ppm.
Sulfuric acid is a very strong, diprotic acid. It is hygroscopic and readily absorbs moisture from air. It is a powerful oxidizing agent and reacts with many metals at high temperatures. Concentrated H2SO4 is also a strong dehydrating agent. Addition of water to concentrated sulfuric acid is a very exothermic reaction and can lead to explosions. C(s) + H2SO4(aq) → 2SO2(g)+2H2O(l) Fe(s) + H2SO4(aq) → H2(g) + FeSO4(aq) Sn(s) + 2 H2SO4(aq) → SnSO4(aq) + 2 H2O(l) + SO2(g) Fi

Methanol is a clear, colorless liquid with a characteristic pungent odor (NTP NIEHS web accessed 2/16/2013). The air odor threshold has been reported as 1500 ppm (approximately 2000mg/m3), much higher than the occupational guidelines. Methanol (methyl alcohol; wood alcohol) is used extensively as a solvent for lacquers, paints, varnishes, cements, inks, dyes, plastics, and various industrial coatings. Large quantities are used in the production of formaldehyde and other chemical de
Loratadine(SCH-29851) is a selective inverse peripheral histamine H1-receptor agonist with an IC50 of >32 μM.IC50 value: 32 uMTarget: H1-receptorLoratadine is a non-sedative antihistamine that inhibits histamine-induced activities of IL-6 and IL-8 secretion in endothelial cells.
2,5-Furandicarboxylic acid is a biomass-derived diacid that can be used to make polymers including polyethylene furandicarboxylate (PEF).
Iodine number maximum of 6, oxirane oxygen minimum of 6.0%.

Peroxide- or thiadiazole-cured CPE exhibits good thermal stability up to 150°C and is much more oil resistant than nonpolar elastomers such as natural rubber or EPDFM. Commercial products are soft when the chlorine content is 28–38%. At more than 45% chlorine content, the material resembles polyvinyl chloride. Higher-molecular-weight polyethylene yields a chlorinated polyethylene that has both high viscosity and tensile strength. often provided for research as a 50% suspension in water, wh
Ethylene-vinyl acetate copolymer (EVA) is a versatile thermoplastic that combines the properties of ethylene and vinyl acetate. This copolymer is characterized by its flexibility, transparency, and resistance to UV radiation and stress-cracking. EVA exhibits excellent adhesion properties, making it an ideal material for various applications. Its low-temperature flexibility and softness enhance its usability in diverse fields.

Tetrahydrofuran (THF) is an industrial solvent widely recognized for its unique combination of useful properties. DuPont THF is better than 99.9% pure with a small (0.025-0.040 wt % ) amount of butylated hydroxytoluene (BHT, 4-methyl-2,6-di-tertbutyl phenol) added as an antioxidant. Tetrahydrofuran is a cycloaliphatic ether and is not ''photochemically reactive'' as defined in Section k of Los Angeles County's Rule 66 (equivalent to Rule 442 of the Southern California Air Pollution Control Dist
