Ninhydrin
Ninhydrin is a chemical compound that is commonly used in forensic science to detect the presence of amino acids. It is a crystalline solid that is soluble in water and has a faint odor. The compound was first discovered in the early 1900s and was initially used as a reagent in organic chemistry. However, its ability to react with amino acids was soon discovered and it became an important tool in forensic analysis.
Key Features:
- Highly sensitive chemical reagent
- Used for detecting fingerprints on porous surfaces
- Produces a purple color when reacting with amino acids in fingerprints
- Can be used on a variety of surfaces, including paper, fabric, and skin
- Easy to use and quick results

Chromium Oxide Green (Chromic Oxide; Chromium(III) Oxide)
Chromium(III) oxide (Cr₂O₃), also known as chromic oxide, is an inorganic compound and a principal oxide of chromium. Renowned for its stability and vibrant green hue, it serves as a green pigment in paints, inks, glasses, and ceramic glazes. When used in glazes, Cr₂O₃ creates a range of green shades, including lime green, kelly green, and black. Its green tones can be modified with small additions of other oxides, like cobalt or copper oxide. Chromium oxide green is also used in polishing pastes, catalysts, and as an advanced green pigment for various industries.
