Chemical Structure
Description
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.
Cytidine Diphosphate (CAS 63-38-7), molecular formula C9H15N3O11P2 and molecular weight 403.18 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Cytidine Diphosphate (C9H15N3O11P2) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. 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 403.18 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), Cytidine Diphosphate 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.
