Chemical Structure

3-Maleimido-benzoic acid CAS 17057-07-7 chemical structure

Description

As a certified reference material (CRM), 3-Maleimido-benzoic acid 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.

3-Maleimido-benzoic acid (CAS 17057-07-7) is a high-purity analytical reference standard with the molecular formula C11H7NO4 and a molecular weight of 217.18 g/mol.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3-Maleimido-benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 217.18 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.
