Chemical Structure

Ac-Ala-Leu-Cys-Asp-Asp-Pro-Arg-Val-Asp-Arg-Trp-Tyr-Cys-Gln-Phe-Val-Glu-Gly-NH2 (Disulfide bond) CAS 1926163-13-4 chemical structure

Description

The occurrence of Ac-Ala-Leu-Cys-Asp-Asp-Pro-Arg-Val-Asp-Arg-Trp-Tyr-Cys-Gln-Phe-Val-Glu-Gly-NH2 (Disulfide bond) is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ac-Ala-Leu-Cys-Asp-Asp-Pro-Arg-Val-Asp-Arg-Trp-Tyr-Cys-Gln-Phe-Val-Glu-Gly-NH2 (Disulfide bond) (CAS 1926163-13-4), molecular formula C97H139N27O29S2 and molecular weight 2211.47 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ac-Ala-Leu-Cys-Asp-Asp-Pro-Arg-Val-Asp-Arg-Trp-Tyr-Cys-Gln-Phe-Val-Glu-Gly-NH2 (Disulfide bond) (C97H139N27O29S2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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