Chemical Structure
Description
Structurally, Atrial Natriuretic Peptide (ANP)(1-28) Alpha (Human, Ovine, Canine) (C127H203N45O39S3) 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 49.0, corresponding to approximately 49 ring(s) or double-bond equivalent(s). With a molecular weight of 3080.44 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.
Atrial Natriuretic Peptide (ANP)(1-28) Alpha (Human, Ovine, Canine) (CAS 91917-63-4) is a high-purity analytical reference standard with the molecular formula C127H203N45O39S3 and a molecular weight of 3080.44 g/mol.
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.
