Compared with other compounds in its class, the molecular weight of 139.17 g/mol gives (2-Ethynylthiazol-4-yl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies (2-Ethynylthiazol-4-yl)methanol (CAS 153028-00-3), a certified reference material (molecular formula C6H5NOS, MW 139.17 g/mol) for analytical method development and quality control.
Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, (2-Ethynylthiazol-4-yl)methanol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 139.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (2-Ethynylthiazol-4-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.
