3-(4-1,2,3-THIADIAZOLYL)PYRIDINE CAS 18212-27-6 chemical structure

Description

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

3-(4-1,2,3-THIADIAZOLYL)PYRIDINE (CAS 18212-27-6) is a high-purity analytical reference standard with the molecular formula C7H5N3S and a molecular weight of 163.20 g/mol.

Structurally, 3-(4-1,2,3-THIADIAZOLYL)PYRIDINE (C7H5N3S) contains a nitrile group, sulfur-containing functionality, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 163.20 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
