Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including SERVA Blue W soluble in water.
CATO supplies SERVA Blue W soluble in water (CAS 5863-46-7), a certified reference material (molecular formula C42H46N3O6S2Na, MW 775.96 g/mol) for analytical method development and quality control.
Structurally, SERVA Blue W soluble in water (C42H46N3O6S2Na) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 21.5, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 775.96 g/mol, it falls into the high-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.
