(S)-(-)-1-(4-bromophenyl)ethylisothiocyanate CAS 745784-02-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-(-)-1-(4-bromophenyl)ethylisothiocyanate.

CATO supplies (S)-(-)-1-(4-bromophenyl)ethylisothiocyanate (CAS 745784-02-5), a certified reference material (molecular formula C9H8BrNS, MW 242.14 g/mol) for analytical method development and quality control.

Structurally, (S)-(-)-1-(4-bromophenyl)ethylisothiocyanate (C9H8BrNS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 242.14 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
