Product Name:5-Nitroisophthalic acid
English Name:5-Nitroisophthalic acid
CAS No.:618-88-2
Aliases:5-Nitro-1,3-benzenedicarboxylic acid, 5-Nitro-m-phthalic acid
Molecular Formula:C8H5NO6
Physical Properties:White to pale yellow crystalline powder. Melting point 260-262°C (decomposition). Slightly soluble in water; soluble in ethanol, ether, and other organic solvents. Stable in air. Exhibits typical properties of organic acids, undergoing esterification, acyl chlorination, reduction, and other reactions.
Uses:Used as an intermediate in the synthesis of sodium amidotrizoate (an X-ray contrast agent) and as a key intermediate in the production of disperse dyes. Through cyanation and amination, it yields 2,6-dicyano-4-nitroaniline, a vital precursor for disperse dyes. It is also widely applied in the fields of pharmaceuticals, agrochemicals, dyes, and pigments.
Technical Specifications:
Purity not less than 98% (HPLC)
Assay (as C8H5NO6) ≥ 98.0%
Loss on drying ≤ 0.5%
Melting point range 260-262°C (decomposition)
