Chemical Structure

2H-Tetrazole-5-thiol CAS 18686-81-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 102.12 g/mol gives 2H-Tetrazole-5-thiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2H-Tetrazole-5-thiol (CAS 18686-81-2) is a high-purity analytical reference standard with the molecular formula CH2N4S and a molecular weight of 102.12 g/mol.

The molecular framework of 2H-Tetrazole-5-thiol (CH2N4S) is characterized by 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
