Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
Fumaric acid-d4 (CAS 194160-45-7), molecular formula C4D4O4 and molecular weight 120.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a carbohydrate-derived structure, Fumaric acid-d4 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Fumaric acid-d4 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.
