Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 232.14 g/mol gives Malic Acid Dimer distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Malic Acid Dimer (CAS 3892-04-4), molecular formula C8H8O8 and molecular weight 232.14 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, Malic Acid Dimer is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.14 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), Malic Acid Dimer 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.
