7-(L-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-D-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 CAS CATO-CPTD788983 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(L-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-D-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷.

7-(L-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-D-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 (CAS CATO-CPTD788983), molecular formula C39H57N7O5 and molecular weight 703.91 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-(L-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-D-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 (C39H57N7O5) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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

CATO manufactures 7-(L-苯丙氨酰基-D-苯丙氨酰基-D-亮氨酰基-D-赖氨酰基)-2-乙酰基-2,7-二氮杂螺[3.5]壬烷 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
