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.
Amyloid β-Protein (1-42) (mouse, rat) (CAS 166090-74-0) is a high-purity analytical reference standard with the molecular formula C199H307N53O59S and a molecular weight of 4418.00 g/mol.
Structurally, Amyloid β-Protein (1-42) (mouse, rat) (C199H307N53O59S) 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 73.0, corresponding to approximately 73 ring(s) or double-bond equivalent(s). With a molecular weight of 4418.00 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).
CATO manufactures Amyloid β-Protein (1-42) (mouse, rat) under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
