Specification

The IUPAC name of Pigment Red 53:1 is barium(2+); 5-chloro-4-methyl-2-[(2Z)-2-(2-oxonaphthalen-1-ylidene)hydrazinyl]benzenesulfonate. With the CAS registry number 5160-02-1, it is also named as 5-Chloro-2-((2-hydroxy-1-naphthalenyl)azo)-4-methylbenzenesulfoni- c acid, barium salt(2:1). The product's categories are organic-metal salt; Ba (Barium) compounds; classes of metal compounds; typical metal compounds. The other registry numbers are 12237-52-4, 12238-39-0, 12238-41-4, 12238-43-6, 24777-23-9, 52627-68-6 and 68894-03-1. It is odorless yellowish-red or reddish-orange powder which is insoluble in acetone, and slightly soluble in ethanol. In addition, this chemical is probably combustible and incompatible with strong oxidizing agents. When heated to decomposition Pigment Red 53:1 emits very toxic fumes of sulfur oxides, nitrogen oxides and chlorine. It can be explosive when suspended in air at specific concentrations. Furthermore, it is not only mainly used for coloring printing ink, rubber and bicycle inner tubes, but also used for coloring stationery and plastic products.

The other characteristics of this product can be summarized as: (1)#H bond acceptors: 12; (2)#H bond donors: 4; (3)#Freely Rotating Bonds: 8; (4)Rotatable Bond Count: 4; (5)Tautomer Count: 9; (6)Exact Mass: 887.946502; (7)MonoIsotopic Mass: 887.946502; (8)Topological Polar Surface Area: 214; (9)Heavy Atom Count: 51; (10)Complexity: 672; (11)Defined Bond StereoCenter Count: 2; (12)Covalently-Bonded Unit Count: 3.

Preparation of Pigment Red 53:1: Salting the CLT acid (2-amino-4-methyl-5-chloro acid) with ammonium hydroxide, diazotization, and coupling with 2-naphthol; And then using rosin and sodium hydroxide for resin-based, then to achieve color lakes by barium chloride; Finally, we can obtain the product by post-processing.
