Chemical Structure
Description
1-Methyl-3,4-dihydroisoquinoline hydrochloride (CAS 26210-39-9), molecular formula C27H34O4S and molecular weight 454.62 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, 1-Methyl-3,4-dihydroisoquinoline hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 454.62 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.
CATO manufactures 1-Methyl-3,4-dihydroisoquinoline hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
