4-Nitrophthalic acid is an aromatic dicarboxylic acid with a nitro substituent, widely used as a precursor in the synthesis of dyes, pharmaceuticals, and agrochemicals, particularly for producing pigments, corrosion inhibitors, and intermediates in organic synthesis. It appears as a pale yellow to off-white crystalline solid with a melting point of 250–252°C and limited solubility in water but better solubility in organic solvents. This chemical carries a **Signal Word: Warning** for its potential skin and eye irritation, requiring standard lab safety measures. Molekula supplies 4-Nitrophthalic acid (CAS 610-27-5, molecular formula O2NC6H3(CO2H)2, MW 211.13) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
