Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,1-Dimethyl-1,2,3,4-tetrahydroisoquinoline-6,7-diol hydrochloride (CAS 33798-64-0), molecular formula C11H15NO2HCl and molecular weight 229.70 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,1-Dimethyl-1,2,3,4-tetrahydroisoquinoline-6,7-diol hydrochloride (C11H15NO2HCl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 229.70 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.
As a certified reference material (CRM), 1,1-Dimethyl-1,2,3,4-tetrahydroisoquinoline-6,7-diol hydrochloride 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.
