3-chloro-5-{[(4-methylphenyl)methyl]sulfanyl}-1,2,4-thiadiazole CAS 1803600-55-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-chloro-5-{[(4-methylphenyl)methyl]sulfanyl}-1,2,4-thiadiazole.

3-chloro-5-{[(4-methylphenyl)methyl]sulfanyl}-1,2,4-thiadiazole (CAS 1803600-55-6) is a high-purity analytical reference standard with the molecular formula C10H9ClN2S2 and a molecular weight of 256.77 g/mol.

The molecular framework of 3-chloro-5-{[(4-methylphenyl)methyl]sulfanyl}-1,2,4-thiadiazole (C10H9ClN2S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
