Chemical Structure

N-Phenylthiourea CAS 103-85-5 chemical structure

Description

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.

CATO supplies N-Phenylthiourea (CAS 103-85-5), a certified reference material (molecular formula C7H8N2S, MW 152.22 g/mol) for analytical method development and quality control.

Owing to a nitrile group, sulfur-containing functionality, an aromatic ring system, N-Phenylthiourea is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 152.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
