Chemical Structure

5-(Methylthio)-1H-pyrazole-3-carbaldehyde CAS 569657-30-3 chemical structure

Description

CATO manufactures 5-(Methylthio)-1H-pyrazole-3-carbaldehyde 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.

CATO supplies 5-(Methylthio)-1H-pyrazole-3-carbaldehyde (CAS 569657-30-3), a certified reference material (molecular formula C5H6N2OS, MW 142.18 g/mol) for analytical method development and quality control.

Owing to an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 5-(Methylthio)-1H-pyrazole-3-carbaldehyde is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.18 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.
