Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Amyloid β-Protein (1-40) (mouse, rat).
CATO supplies Amyloid β-Protein (1-40) (mouse, rat) (CAS 144409-98-3), a certified reference material (molecular formula C190H291N51O57S, MW 4234.00 g/mol) for analytical method development and quality control.
Structurally, Amyloid β-Protein (1-40) (mouse, rat) (C190H291N51O57S) 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 71.0, corresponding to approximately 71 ring(s) or double-bond equivalent(s). With a molecular weight of 4234.00 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).
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.
As a certified reference material (CRM), Amyloid β-Protein (1-40) (mouse, rat) 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.
