Chemical Structure

4-Methyl-3-phenylisothiazol-5-amine CAS 91818-68-7 chemical structure

Description

4-Methyl-3-phenylisothiazol-5-amine (CAS 91818-68-7) is a high-purity analytical reference standard with the molecular formula C10H10N2S and a molecular weight of 190.26 g/mol.

Structurally, 4-Methyl-3-phenylisothiazol-5-amine (C10H10N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 190.26 g/mol, it falls into the medium-molecular-weight range. 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.
