Chemical Structure

4-Nitrophthalimide CAS 89-40-7 chemical structure

Description

4-Nitrophthalimide (CAS 89-40-7), molecular formula C8H4N2O4 and molecular weight 192.13 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 4-Nitrophthalimide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 192.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4-Nitrophthalimide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
