Chemical Structure

N-Tos-D/L Valine CAS 32013-47-1 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 271.33 g/mol gives N-Tos-D/L Valine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N-Tos-D/L Valine (CAS 32013-47-1), a certified reference material (molecular formula C12H17NO4S, MW 271.33 g/mol) for analytical method development and quality control.

Structurally, N-Tos-D/L Valine (C12H17NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 271.33 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures N-Tos-D/L Valine 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.
