Chemical Structure

2-Isocyanato-3-methylthiophene CAS 76537-01-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Isocyanato-3-methylthiophene.

2-Isocyanato-3-methylthiophene (CAS 76537-01-4) is a high-purity analytical reference standard with the molecular formula C6H5NOS and a molecular weight of 139.17 g/mol.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Isocyanato-3-methylthiophene 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).

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.

CATO manufactures 2-Isocyanato-3-methylthiophene 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.
