Chemical Structure

(Des-acetyl)-α-MSH CAS 53697-27-1 chemical structure

Description

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

(Des-acetyl)-α-MSH (CAS 53697-27-1) is a high-purity analytical reference standard with the molecular formula C75H107N21O18S and a molecular weight of 1622.87 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (Des-acetyl)-α-MSH is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1622.87 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.

CATO manufactures (Des-acetyl)-α-MSH 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.
