4-Methyl-3,4-dihydroisoquinoline CAS 86457-01-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Methyl-3,4-dihydroisoquinoline.

4-Methyl-3,4-dihydroisoquinoline (CAS 86457-01-4), molecular formula C10H11N and molecular weight 145.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methyl-3,4-dihydroisoquinoline is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.20 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), 4-Methyl-3,4-dihydroisoquinoline 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.
