PARANITRANILINE RED Meaning and Definition

1. Paranitraniline red, also known as PNA red, is a synthetic dye derived from the chemical compound paranitraniline. It falls under the category of organic pigments and is primarily used as a coloring agent in various industries.

   Paranitraniline red is characterized by its bright and intense red color, making it popular for numerous applications such as paints, inks, textiles, and plastics. The dye is known for its excellent colorfastness, which refers to its ability to resist fading or bleeding when exposed to light or chemicals. This attribute ensures that products containing paranitraniline red retain their vibrant hue over time.

   Chemically, paranitraniline red consists of molecules with a para-nitro group (-NO2) attached to an aniline (C6H5NH2) structure. This specific molecular arrangement gives the dye its distinctive color and desirable properties. When exposed to light, the molecules absorb certain wavelengths, thereby reflecting red light and appearing red to the human eye.

   Paranitraniline red is typically synthesized in a laboratory using various chemical reactions involving paranitrobenzene, aniline, and other reagents. It can also be produced by modifying other similar red dyes through chemical transformations.

   Overall, due to its vivid color, good colorfastness, and versatility, paranitraniline red has become a widely used dye in multiple industries, contributing to the production of visually appealing and durable products.

Etymology of PARANITRANILINE RED

The word "paranitraniline red" is derived from the combination of three components: "para-", "nitraniline", and "red".

1. "Para-" is a prefix derived from the Greek word "pará", meaning "beside" or "alongside". In chemistry, this prefix is used to indicate the position of a substituent or functional group on an aromatic compound, particularly on a benzene ring. In the case of "paranitraniline", "para-" signifies that the nitraniline group is attached to the fourth carbon atom of the benzene ring.

2. "Nitraniline" is a compound composed of two parts: "nitro-" and "aniline". "Nitro-" is derived from the Latin word "nitrum", which means "saltpeter".
