Chemical Structure

[Asp28]-Thymalfasin CAS CATO-C4X-189810 chemical structure

Description

As a certified reference material (CRM), [Asp28]-Thymalfasin 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.

CATO supplies [Asp28]-Thymalfasin (CAS CATO-C4X-189810), a certified reference material (molecular formula C129H214N32O56, MW 3109.26 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, [Asp28]-Thymalfasin is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 3109.26 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.
