(3-Methylisothiazol-5-yl)methanol CAS 17265-60-0 chemical structure

Description

CATO manufactures (3-Methylisothiazol-5-yl)methanol 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.

(3-Methylisothiazol-5-yl)methanol (CAS 17265-60-0), molecular formula C5H7NOS and molecular weight 129.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (3-Methylisothiazol-5-yl)methanol (C5H7NOS) 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.
