Chemical Structure
Description
The occurrence of Pentamethylphenylacetonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pentamethylphenylacetonitrile (CAS 34688-70-5) is a high-purity analytical reference standard with the molecular formula C13H17N and a molecular weight of 187.28 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Pentamethylphenylacetonitrile is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 187.28 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Pentamethylphenylacetonitrile meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
