Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including ML RR-S2 CDA Sodium Salt.
ML RR-S2 CDA Sodium Salt (CAS 1638750-95-4), molecular formula C20H22N10O10P2S2Na and molecular weight 711.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, ML RR-S2 CDA Sodium Salt (C20H22N10O10P2S2Na) contains a flavonoid core, an amide group, a sulfone group, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 711.51 g/mol, it falls into the high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
