α-CGRP (8-37) (human) CAS 119911-68-1

Description

Compared with other compounds in its class, the molecular weight of 3125.63 g/mol gives α-CGRP (8-37) (human) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

α-CGRP (8-37) (human) (CAS 119911-68-1) is a high-purity analytical reference standard with the molecular formula C139H230N44O38 and a molecular weight of 3125.63 g/mol.

α-CGRP (8-37) (human) (C139H230N44O38) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), α-CGRP (8-37) (human) 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.
