Chemical Structure

L-(+)-Cystathionine CAS 56-88-2 chemical structure

Description

L-(+)-Cystathionine (CAS 56-88-2), molecular formula C7H14N2O4S and molecular weight 222.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, L-(+)-Cystathionine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 222.26 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.

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 L-(+)-Cystathionine 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.
