2-[2-(Phenylsulfanyl)pyridin-3-yl]-1,3-benzothiazole CAS 339112-89-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[2-(Phenylsulfanyl)pyridin-3-yl]-1,3-benzothiazole.

CATO supplies 2-[2-(Phenylsulfanyl)pyridin-3-yl]-1,3-benzothiazole (CAS 339112-89-9), a certified reference material (molecular formula C18H12N2S2, MW 320.43 g/mol) for analytical method development and quality control.

Structurally, 2-[2-(Phenylsulfanyl)pyridin-3-yl]-1,3-benzothiazole (C18H12N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 320.43 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

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.
