C-Reactive Protein (CRP) (201-206) H-Lys-Pro-Gln-Leu-Trp-Pro-OH CAS 130348-99-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including C-Reactive Protein (CRP) (201-206) H-Lys-Pro-Gln-Leu-Trp-Pro-OH.

C-Reactive Protein (CRP) (201-206) H-Lys-Pro-Gln-Leu-Trp-Pro-OH (CAS 130348-99-1) is a high-purity analytical reference standard with the molecular formula C38H57N9O8 and a molecular weight of 767.91 g/mol.

The molecular framework of C-Reactive Protein (CRP) (201-206) H-Lys-Pro-Gln-Leu-Trp-Pro-OH (C38H57N9O8) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
