Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-5-N-ethylcarboxamide-2,3-O-isopropylidene adenosine (CAS 120225-75-4) is a high-purity analytical reference standard with the molecular formula C15H19ClN6O4 and a molecular weight of 382.80 g/mol.
Based on its molecular formula C15H19ClN6O4, 2-Chloro-5-N-ethylcarboxamide-2,3-O-isopropylidene adenosine contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 382.80 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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.
