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 Cys-Gly-His-Gly-Asn-Lys-Ser-Amyloid β-Protein (33-40) trifluoroacetate salt.
Cys-Gly-His-Gly-Asn-Lys-Ser-Amyloid β-Protein (33-40) trifluoroacetate salt (CAS 1802078-22-3) is a high-purity analytical reference standard with the molecular formula C58H99N19O18S2C2HF3O2 and a molecular weight of 1528.69 g/mol.
Structurally, Cys-Gly-His-Gly-Asn-Lys-Ser-Amyloid β-Protein (33-40) trifluoroacetate salt (C58H99N19O18S2C2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 1528.69 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), Cys-Gly-His-Gly-Asn-Lys-Ser-Amyloid β-Protein (33-40) trifluoroacetate salt 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.
