Chemical Structure
Description
As a certified reference material (CRM), (3-Methyloxetan-3-yl)methanethiol 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.
(3-Methyloxetan-3-yl)methanethiol (CAS 63991-91-3), molecular formula C5H10OS and molecular weight 118.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-Methyloxetan-3-yl)methanethiol (C5H10OS) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
