Sodium borohydride reduces aldehydes and ketones to give the related alcohols. This reaction is used in the production of various antibiotics including chloramphenicol, dihydrostreptomycin, and thiophenicol. Various steroids and vitamin A are prepared using sodium borohydride in at least one step.

Sodium borohydride is used as reducing agent in the synthesis of gold nanoparticles.

Methyl vanillate was used to investigate the volatile compounds of heather honeys from Calluna vulgaris and Erica arborea^[2].

Methyl vanillate is a volatile compound present in cloudberries (Rubus Chamaemorus.)

5. ^{INFORMATION OF GUANIDINE HYDROCHLORIDE: arious publications cite the use of Guanidine Hydrochloride for purification of proteins and nucleic acids. It is also useful for denaturation and refolding of proteins as well as in the recovery of periplasmic proteins and isolation of RNA. At higher concentrations, this strong denaturant has been reported to solubilize denatured insoluble proteins such as inclusion bodies. -SCBT Publication Review}
6. ^{DISCRIPTION:Guanidine Hydrochloride is a powerful, chaotropic agent which is widely used for purification of proteins and nucleic acids. Guanidine Hydrochloride is useful for denaturation and refolding of proteins as well as in the recovery of periplasmic proteins and isolation of RNA. At higher concentrations, this strong denaturant has been reported to solubilize denatured insoluble proteins such as inclusion bodies. When utilized at lower concentrations, Guanidine Hydrochloride is noted to be useful in prompting the refolding of denatured proteins. Guanidine Hydrochloride is also been reported to allow return of enzymatic activity in protocols using Guanidine Hydrochloride as a first step. Guanidine Hydrochloride is an inhibitor of RNase.}
7. ^{USES:To make an 8M solution in water, heat the solution to 35°C for approximately 30 minutes. The maximum solubility of guanidine hydrochloride in water at room temperature is approximately 6M.}
8. ^{Note: Guanidine HCl may clump during storage. It may appear as a free-flowing crystalline powder, a free-flowing powder with solid material dispersed throughout, or a solid. The quality of the product does not appear to be affected and solutions prepared from the free-flowing and lumpy guanidine HCl appear identical.}

1% and 2% uranyl acetate solutions are used as an indicator, and a titrant in stronger concentrations in analytical chemistry, as it forms an insoluble salt with sodium (the vast majority of sodium salts are water-soluble). Uranyl acetate solutions show evidence of being sensitive to light, especially UV, and will precipitate if exposed.

Uranyl acetate is also used in a standard test-American Association of State Highway and Transportation Officials (AASHTO) Designation T 299-for alkali-silica reactivity in aggregates (crushed stone or gravel) being considered for use in cement concrete.

Uranyl acetate dihydrate has been used as a starting reagent in experimental inorganic chemistry, for example, [UO₂Cl₂(THF)₂] (THF = tetrahydrofuran).
SAFTYUranyl acetate is both radioactive and toxic. Normal commercial stocks prepared from depleted have a typical specific activity of 0.37-0.51 microcuries (14-19 kBq) per gram. This is a very mild level of radioactivity and is not sufficient to be harmful while the material remains external to the body.

Uranyl acetate is very toxic if ingested, inhaled as dust or by skin contact if skin is cut or abraded. The toxicity is due to the combined effect of chemical toxicity and mild radioactivity and there is a danger of cumulative effects from long term exposure.
