2,5-Diaminobenzene-1,4-diol (CAS 10325-89-0), molecular formula C6H8N2O2 and molecular weight 140.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,5-Diaminobenzene-1,4-diol (C6H8N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 140.14 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
