Gelatin

Gelatin is a translucent, colorless, brittle, nearly tasteless solid substance, derived from the collagen inside animals' skin and bones. It is commonly used as a gelling agent in food, pharmaceuticals, photography, and cosmetic manufacturing. Substances containing gelatin or functioning in a similar way are called gelatinous. Gelatin is an irreversibly hydrolysed form of collagen. It is found in some gummy candies as well as other products such as marshmallows, gelatin dessert, and some low-fat yogurt.

Hexamethyldisilazane

Hexamethyldisilazane is an organosilicon compound. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms. This colorless liquid is a reagent and a precursor to bases that are popular in organic synthesis and organometallic chemistry. In photolithography, hexamethyldisilazane is often used in as an adhesion promoter for photoresist. In electron microscopy, it can be used as an alternative to critical point drying during sample preparation. In pyrolysis-gas chromatography-mass spectrometry, hexamethyldisilazane is added to the analyte to create sylilated diagnostic products during pyrolysis, in order to enhance detectability of compounds with polar functional groups.

Hydroxylamine

Hydroxylamine is an inorganic compound. It is used to prepare oximes, an important functional group. It is also an intermediate in biological nitrification. Hydroxylamine and its salts are commonly used as reducing agents in a myriad of organic and inorganic reactions. They can also act as antioxidants for fatty acids. Some non-chemical uses include removal of hair from animal hides and photography developing solutions. It is used as an irreversible inhibitor of the oxygen-evolving complex of photosynthesis on account of its similar structure to water. In the semiconductor industry, hydroxylamine is often a component in the "resist stripper" which removes photoresist after lithography.

Hydroxylamine Sulfate

Hydroxylamine sulfate is the sulfuric acid salt of hydroxylamine. It is used in organic synthesis to convert aldehydes and ketones to oximes, carboxylic acids and their derivatives to hydroxamic acids, isocyanates to N-hydroxyureas and nitriles to amidoximes. It is also used to generate hydroxylamine-O-sulfonic acid from oleum or chlorosulfuric acid. It is used in the production of anti-skinning agents, pharmaceuticals, rubber, textiles, plastics and detergents. It is a starting material for some insecticides, herbicides and growth regulators. It is used in photography as a stabiliser for colour developers and as an additive in photographic emulsions in colour film.

Hydroxylammonium Chloride

Hydroxylammonium chloride is the hydrochloric acid salt of hydroxylamine. It is a biological intermediate in the nitrification and in the anammox which are important in the nitrogen cycle in soil and in wastewater treatment. It is used in organic synthesis for preparation of oximes and hydroxamic acids from carboxylic acids, N- and O- substituted hydroxyamines, and addition reactions of carbon-carbon double bond. In surface treatments, it is used in the preparation of anti-skinning agents, corrosion inhibitors, and cleaner additives. It is also a starting material for pharmaceuticals and agrochemicals manufacturing. In the rubber and plastics industries, it is an antioxidant, vulcanization accelerator, and radical scavenger. It is also used as a fixative for textile dyes, auxiliary in some dyeing processes, as a metal extraction and flotation aid, as an antioxidant in fatty acids and soaps, and as a color stabilizer and emulsion additive in color films.

Hydroxypropyl Methylcellulose

Hydroxypropyl methylcellulose is a semisynthetic, inert, viscoelastic polymer used as an ophthalmic lubricant, as well as an excipient and controlled-delivery component in oral medicaments, found in a variety of commercial products. As a food additive, hydroxypropyl methylcellulose is an emulsifier, thickening and suspending agent, and an alternative to animal gelatin. It is used primarily in construction materials like tile adhesives and renders where it is used as a rheology modifier and water retention agent. Hydroxypropyl methylcellulose solutions were patented as a semisynthetic substitute for tear-film. In addition to its use in ophthalmic liquids, hydroxypropyl methylcellulose has been used as an excipient in oral tablet and capsule formulations, where, depending on the grade, it functions as controlled release agent to delay the release of a medicinal compound into the digestive tract. It is also used as a binder and as a component of tablet coatings. Other applications include paints, cosmetics and detergents.

Imidazole

Imidazole is an organic compound. This aromatic heterocyclic is a diazole and is classified as an alkaloid. Imidazole refers to the parent compound whereas imidazoles are a class of heterocycles with similar ring structure but varying substituents. This ring system is present in important biological building blocks such as histidine, and the related hormone histamine. It can serve as a base and as a weak acid. Many drugs contain an imidazole ring, such as antifungal drugs and nitroimidazole. It has been used extensively as a corrosion inhibitor on certain transition metals, such as copper. Many compounds of industrial and technological importance contain imidazole derivatives. The thermostable polybenzimidazole PBI contains imidazole fused to a benzene ring and linked to a benzene, and acts as a fire retardant.It can also be found in various compounds which are used for photography and electronics.

Krypton

Krypton is a noble gas, occurs in trace amounts in the atmosphere, is isolated by fractionally distilling liquified air, and is often used with other rare gases in fluorescent lamps. Krypton's multiple emission lines make ionized krypton gas discharges appear whitish, which in turn makes krypton-based bulbs useful in photography as a brilliant white light source. It is thus used in some types of photographic flashes used in high speed photography. It has an important role in production and usage of the krypton fluoride laser. The laser has been important in the nuclear fusion energy research community in confinement experiments. In experimental particle physics, liquid krypton is used to construct quasi-homogeneous electromagnetic calorimeters.

Lead Nitrate

Lead Nitrate is a granular white crystal powder with the chemical formula Pb (NO3)2. It is produced by dissolving metallic lead in aqueous nitric acid. Lead nitrate is the raw material for the pigments for lead paints, lead compounds, nylon fiber stabilizer, textile mordant, and leather tanning agent.
