Chemical Structure
Description
(²H₃)furan-2-(²H)carboxylic acid (CAS 1256380-81-0), molecular formula C5D4O3 and molecular weight 116.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (²H₃)furan-2-(²H)carboxylic acid (C5D4O3) contains deuterium isotope labeling, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 116.11 g/mol, it falls into the low-molecular-weight range. 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).
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.
CATO manufactures (²H₃)furan-2-(²H)carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
