Description

The occurrence of 1H-Pyridine-2-thione 2(1H)-Pyridinethione 2-Mercaptopyridine 2-pyridinethiol 2-pyridinethione 2-pyridyl mercaptan 2-thiopyridine 2-thiopyridone 2637-34-5 Alrithiol-2 NSC 41337 WR 608 pyrid-2-thione is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1H-Pyridine-2-thione 2(1H)-Pyridinethione 2-Mercaptopyridine 2-pyridinethiol 2-pyridinethione 2-pyridyl mercaptan 2-thiopyridine 2-thiopyridone 2637-34-5 Alrithiol-2 NSC 41337 WR 608 pyrid-2-thione (CAS 2637-34-5) is a high-purity analytical reference standard with the molecular formula C5H11NS and a molecular weight of 117.21 g/mol.

The molecular framework of 1H-Pyridine-2-thione 2(1H)-Pyridinethione 2-Mercaptopyridine 2-pyridinethiol 2-pyridinethione 2-pyridyl mercaptan 2-thiopyridine 2-thiopyridone 2637-34-5 Alrithiol-2 NSC 41337 WR 608 pyrid-2-thione (C5H11NS) 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.

As a certified reference material (CRM), 1H-Pyridine-2-thione 2(1H)-Pyridinethione 2-Mercaptopyridine 2-pyridinethiol 2-pyridinethione 2-pyridyl mercaptan 2-thiopyridine 2-thiopyridone 2637-34-5 Alrithiol-2 NSC 41337 WR 608 pyrid-2-thione 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.
