L-Threonyl-L-arginine hemisulfate salt CAS 108320-96-3

Description

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.

L-Threonyl-L-arginine hemisulfate salt (CAS 108320-96-3), molecular formula C10H21N5O4H2O4S and molecular weight 373.38 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of L-Threonyl-L-arginine hemisulfate salt (C10H21N5O4H2O4S) is characterized by a carbohydrate-derived structure, an amide group, a sulfone group. 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-Threonyl-L-arginine hemisulfate salt 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.
