But-2-ynyl-p-tolyl-amine hydrochloride CAS 435345-29-2

Description

Compared with other compounds in its class, the molecular weight of 159.23 g/mol gives But-2-ynyl-p-tolyl-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

But-2-ynyl-p-tolyl-amine hydrochloride (CAS 435345-29-2), molecular formula C11H13N and molecular weight 159.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of But-2-ynyl-p-tolyl-amine hydrochloride (C11H13N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
