Pigment Red 2 , with CAS number of 6041-94-7, can be called 2-naphthalenecarboxamide, 4-[(E)-2-(2,5-dichlorophenyl)diazenyl]-3-hydroxy-N-phenyl- ; 2-naphthalenecarboxamide, 4-[(E)-(2,5-dichlorophenyl)azo]-3-hydroxy-N-phenyl- ; 2-Naphthalenecarboxamide, 4-[(2,5-dichlorophenyl)azo]-3-hydroxy-N-phenyl- ; 4-[(E)-(2,5-dichlorophenyl)diazenyl]-3-hydroxy-N-phenylnaphthalene-2-carboxamide ; 4-[(E)-(2,5-Dichlorophenyl)diazenyl]-3-hydroxy-N-phenyl-2-naphthamide .It is a yellowish red or dark red powder, it can be explosive when suspended in air at specific concentrations. Pigment Red 2 (CAS NO.6041-94-7) is an azo compound. connecting with diazo, azido can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides and strong oxidizing or reducing agents. | |
| Storage Temperature: | Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage. | |
| Usage: | Inks, dyes. | |
