H-p-Chloro-Phe-D-Cys-β-(3-pyridyl)-Ala-D-Trp-Lys-Val-Cys-p-chloro-Phe-NH2 trifluoroacetate salt (Disulfide bond) CAS 209006-05-3 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 H-p-Chloro-Phe-D-Cys-β-(3-pyridyl)-Ala-D-Trp-Lys-Val-Cys-p-chloro-Phe-NH2 trifluoroacetate salt (Disulfide bond).

CATO supplies H-p-Chloro-Phe-D-Cys-β-(3-pyridyl)-Ala-D-Trp-Lys-Val-Cys-p-chloro-Phe-NH2 trifluoroacetate salt (Disulfide bond) (CAS 209006-05-3), a certified reference material (molecular formula C54H66Cl2N12O8S2C2HF3O2, MW 1260.24 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, H-p-Chloro-Phe-D-Cys-β-(3-pyridyl)-Ala-D-Trp-Lys-Val-Cys-p-chloro-Phe-NH2 trifluoroacetate salt (Disulfide bond) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1260.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), H-p-Chloro-Phe-D-Cys-β-(3-pyridyl)-Ala-D-Trp-Lys-Val-Cys-p-chloro-Phe-NH2 trifluoroacetate salt (Disulfide bond) 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.
