Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 150.52 g/mol gives 2-Chloromaleic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Chloromaleic acid (CAS 617-43-6), a certified reference material (molecular formula C4H3ClO4, MW 150.52 g/mol) for analytical method development and quality control.
The molecular framework of 2-Chloromaleic acid (C4H3ClO4) is characterized by a carbohydrate-derived structure, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 2-Chloromaleic 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.
