Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Somatostatin-28 (H-4955.0500).
Somatostatin-28 (H-4955.0500) (CAS 73032-94-7), molecular formula C137H207N41O39S3 and molecular weight 3148.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Somatostatin-28 (H-4955.0500) (C137H207N41O39S3) 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. 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), Somatostatin-28 (H-4955.0500) 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.
