2-Methyl-1-((4-methylthiazol-2-yl)thio)propan-2-ol CAS 1183023-53-1

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

2-Methyl-1-((4-methylthiazol-2-yl)thio)propan-2-ol (CAS 1183023-53-1), molecular formula C8H13NOS2 and molecular weight 203.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Methyl-1-((4-methylthiazol-2-yl)thio)propan-2-ol (C8H13NOS2) is characterized by an amide group, sulfur-containing functionality, 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.

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.
