72122-63-5 beta-Casomorphin 5 Glycine, N-(1-(N-(1-L-tyrosyl-L-prolyl)-L-phenylalanyl)-L-prolyl)- Casomorphin, pro(4)- Deprolorphin D-Pro(4)-casomorphin L-Pro(4)-casomorphin 4-Pro-casomorphin (D-Tyr(1))CM-5 Tyrosyl-prolyl-phenylalanyl-prolylglycine Tyr-pro-phe-pro-gly (CAS 72122-63-5), molecular formula C30H49N5O7 and molecular weight 591.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 72122-63-5 beta-Casomorphin 5 Glycine, N-(1-(N-(1-L-tyrosyl-L-prolyl)-L-phenylalanyl)-L-prolyl)- Casomorphin, pro(4)- Deprolorphin D-Pro(4)-casomorphin L-Pro(4)-casomorphin 4-Pro-casomorphin (D-Tyr(1))CM-5 Tyrosyl-prolyl-phenylalanyl-prolylglycine Tyr-pro-phe-pro-gly (C30H49N5O7) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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.

As a certified reference material (CRM), 72122-63-5 beta-Casomorphin 5 Glycine, N-(1-(N-(1-L-tyrosyl-L-prolyl)-L-phenylalanyl)-L-prolyl)- Casomorphin, pro(4)- Deprolorphin D-Pro(4)-casomorphin L-Pro(4)-casomorphin 4-Pro-casomorphin (D-Tyr(1))CM-5 Tyrosyl-prolyl-phenylalanyl-prolylglycine Tyr-pro-phe-pro-gly 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.
