Chemical Structure

Isothiazol-5-yl-methanol CAS 1710-66-3 chemical structure

Description

The occurrence of Isothiazol-5-yl-methanol is closely related to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Isothiazol-5-yl-methanol (CAS 1710-66-3), molecular formula C4H5NOS and molecular weight 115.15 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H5NOS, Isothiazol-5-yl-methanol contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 115.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Isothiazol-5-yl-methanol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
