Description

PT5II901IF 540-23-8 p-Toluidine hydrochloride Benzenamine, 4-methyl-, hydrochloride p-Toluidine, hydrochloride p-Toluidinium chloride Benzenamine, 4-methyl-, hydrochloride (1:1) 4-Aminotoluene hydrochloride CCRIS 6104 EINECS 208-740-8 4-Methylaniline hydrochloride p-Methylanilinium chloride 4-Methylanilinium chloride 4-Methylbenzenamine hydrochloride UNII-PT5II901IF (CAS 540-23-8), molecular formula C7H15NHCl and molecular weight 149.66 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to chlorine substitution, PT5II901IF 540-23-8 p-Toluidine hydrochloride Benzenamine, 4-methyl-, hydrochloride p-Toluidine, hydrochloride p-Toluidinium chloride Benzenamine, 4-methyl-, hydrochloride (1:1) 4-Aminotoluene hydrochloride CCRIS 6104 EINECS 208-740-8 4-Methylaniline hydrochloride p-Methylanilinium chloride 4-Methylanilinium chloride 4-Methylbenzenamine hydrochloride UNII-PT5II901IF is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 149.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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

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.
