Amyloid β-Protein (33-42) CAS 178949-81-0

Description

As a certified reference material (CRM), Amyloid β-Protein (33-42) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Amyloid β-Protein (33-42) (CAS 178949-81-0), molecular formula C41H74N10O11S and molecular weight 915.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Amyloid β-Protein (33-42) (C41H74N10O11S) 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 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 915.17 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).

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.
