Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 405.79 g/mol gives 2-3-5-Tri-O-acetylcytidine HCI distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-3-5-Tri-O-acetylcytidine HCI (CAS 63639-21-4) is a high-purity analytical reference standard with the molecular formula C15H19N3O8HCl and a molecular weight of 405.79 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-3-5-Tri-O-acetylcytidine HCI is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 405.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-3-5-Tri-O-acetylcytidine HCI 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.
