Chemical Structure

Phenylhydrazinocarbodithioic Acid Ammonium Salt CAS 18995-90-9 chemical structure

Description

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, Phenylhydrazinocarbodithioic Acid Ammonium Salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Phenylhydrazinocarbodithioic Acid Ammonium Salt (CAS 18995-90-9), molecular formula C7H7N2S2H4N and molecular weight 201.31 g/mol, is a CATO reference standard with documented purity and traceability.

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.
