Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Ala11·22·2?)-VIP (human, mouse, rat).
(Ala11·22·2?)-VIP (human, mouse, rat) (CAS 291524-04-4) is a high-purity analytical reference standard with the molecular formula C139H231N43O39S and a molecular weight of 3160.70 g/mol.
Structurally, (Ala11·22·2?)-VIP (human, mouse, rat) (C139H231N43O39S) 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 46.0, corresponding to approximately 46 ring(s) or double-bond equivalent(s). With a molecular weight of 3160.70 g/mol, it falls into the 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.
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.
