Chemical Structure

1-Naphthyl Isothiocyanate CAS 551-06-4 chemical structure

Description

As a certified reference material (CRM), 1-Naphthyl Isothiocyanate 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.

CATO supplies 1-Naphthyl Isothiocyanate (CAS 551-06-4), a certified reference material (molecular formula C11H7NS, MW 185.24 g/mol) for analytical method development and quality control.

Structurally, 1-Naphthyl Isothiocyanate (C11H7NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 185.24 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.

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.
