2-Methoxythiazole CAS 14542-13-3 chemical structure

Description

2-Methoxythiazole (CAS 14542-13-3) is a high-purity analytical reference standard with the molecular formula C4H5NOS and a molecular weight of 115.15 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-Methoxythiazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 115.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-Methoxythiazole 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.
