Chemical Structure

Cholecystokinin Precursor (24-32) (rat) H-Val-Pro-Val-Glu-Ala-Val-Asp-Pro-Met-OH CAS 99291-20-0 chemical structure

Description

The occurrence of Cholecystokinin Precursor (24-32) (rat) H-Val-Pro-Val-Glu-Ala-Val-Asp-Pro-Met-OH 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.

Cholecystokinin Precursor (24-32) (rat) H-Val-Pro-Val-Glu-Ala-Val-Asp-Pro-Met-OH (CAS 99291-20-0), molecular formula C42H69N9O14S and molecular weight 956.11 g/mol, is a CATO reference standard with documented purity and traceability.

Cholecystokinin Precursor (24-32) (rat) H-Val-Pro-Val-Glu-Ala-Val-Asp-Pro-Met-OH (C42H69N9O14S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Cholecystokinin Precursor (24-32) (rat) H-Val-Pro-Val-Glu-Ala-Val-Asp-Pro-Met-OH 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.
