Chemical Structure

L-Buthionine Sulfoxide CAS 199982-01-9 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.

L-Buthionine Sulfoxide (CAS 199982-01-9) is a high-purity analytical reference standard with the molecular formula C8H17NO3S and a molecular weight of 207.29 g/mol.

The molecular framework of L-Buthionine Sulfoxide (C8H17NO3S) is characterized by an amide group, a sulfone group, a carboxylic acid 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. 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 L-Buthionine Sulfoxide 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.
