Hydroxylamine hydrochloride (hhcl) is used in organic synthesis for preparation of oximes and hydroxamic acids from caroxylic acids, n- and o- substituted hydroxylamines, and addition reactions of carbon carbon double bond.
during the acetyl bromide method of extracting lignin from lignocellulosic biomass, hydroxylamine hydrochloide can be used to remove bromine and polybromide from the solution.
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 floatation aid, as an anti oxidant in fatty acids and soaps , and as a colour stabilizer and emulsion additive in color films .
it is also used in analytic chemistry in the analysis of iron in the water.

This colourless liquid is poorly soluble in water but miscible with most organic solvents. It is a derivative of benzene, consisting of two adjacent chlorine atoms. 1,2-Dichlorobenzene.

Isopropyl alcohol is a colorless, flammable chemical compound with a strong odor. As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms.

Trifluoroacetic acid (TFA) is a strong acid with many uses, including as a catalyst, solvent, and reagent in organic synthesis. It's also used in pharmaceuticals, electronics, and analytical chemistry. Uses in organic synthesis

• Catalyst: TFA is used as a catalyst in many reactions, including rearrangements, oxidations, reductions, and condensations 
• Solvent: TFA is a good solvent for organic compounds and water 
• Reagent: TFA is used to cleave protecting groups, such as Boc and Z(OMe) 
• Deprotecting agent: TFA is used as a final deprotecting reagent in the Fmoc/t-Bu strategy 

Other uses

• Theranostic agent: TFA can be used as a theranostic agent in 19F-MRI to image chemical ablation of solid tissue 
• Analytical chemistry: TFA is used in analytical chemistry 

TFA is low to moderately toxic to many organisms and can accumulate in the environment.
