Description

CATO manufactures 5-Mercapto-1,3-dimethyl-1H-pyrazole-4-carbonitrile 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.

5-Mercapto-1,3-dimethyl-1H-pyrazole-4-carbonitrile (CAS 87573-92-0), molecular formula C6H7N3S and molecular weight 153.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, 5-Mercapto-1,3-dimethyl-1H-pyrazole-4-carbonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 153.20 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.

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.
