3-Amino-6-methylpyridazine-4-thiol CAS 18591-81-6 chemical structure

Description

CATO supplies 3-Amino-6-methylpyridazine-4-thiol (CAS 18591-81-6), a certified reference material (molecular formula C5H7N3S, MW 141.19 g/mol) for analytical method development and quality control.

The molecular framework of 3-Amino-6-methylpyridazine-4-thiol (C5H7N3S) is characterized by a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 3-Amino-6-methylpyridazine-4-thiol 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.
