Description
OZF8J4VAIK 35803-45-3 Uracil C-13, 2- UNII-OZF8J4VAIK Uracil-(2-13C) Uracil (2-13C) [JAN] Uracil (2-13C) 2,4(1H,3H)-Pyrimidinedione-2-13c (CAS 35803-45-3), molecular formula C3[13C]H4N2O2 and molecular weight 113.08 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, OZF8J4VAIK 35803-45-3 Uracil C-13, 2- UNII-OZF8J4VAIK Uracil-(2-13C) Uracil (2-13C) [JAN] Uracil (2-13C) 2,4(1H,3H)-Pyrimidinedione-2-13c (C3[13C]H4N2O2) 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 113.08 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
