Chemical Structure
Description
OxythiamineDISCONTINUED. Please see O878508. (CAS 136-16-3) is a high-purity analytical reference standard with the molecular formula C12H16N3O2SHClCl and a molecular weight of 338.25 g/mol.
The molecular framework of OxythiamineDISCONTINUED. Please see O878508. (C12H16N3O2SHClCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.
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 OxythiamineDISCONTINUED. Please see O878508. 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.
