Description
CATO manufactures β-Endorphin (6-31) (human) 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.
CATO supplies β-Endorphin (6-31) (human) (CAS 77761-27-4), a certified reference material (molecular formula C131H218N34O40, MW 2909.38 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, β-Endorphin (6-31) (human) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 2909.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
