138470-70-9 5-(Dimethylamino)-1-[4-(2-methylbenzamido)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine hydrochloride Mozavaptan hydrochloride N-[4-(5-Dimethylamino-2,3,4,5-tetrahydro-1-benzazepine-1-carbonyl)phenyl]-2-methylbenzamide hydrochloride OPC 31260 hydrochloride CAS 138470-70-9 chemical structure

Description

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO supplies 138470-70-9 5-(Dimethylamino)-1-[4-(2-methylbenzamido)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine hydrochloride Mozavaptan hydrochloride N-[4-(5-Dimethylamino-2,3,4,5-tetrahydro-1-benzazepine-1-carbonyl)phenyl]-2-methylbenzamide hydrochloride OPC 31260 hydrochloride (CAS 138470-70-9), a certified reference material (molecular formula C27H29N3O2HCl, MW 464.01 g/mol) for analytical method development and quality control.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 138470-70-9 5-(Dimethylamino)-1-[4-(2-methylbenzamido)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine hydrochloride Mozavaptan hydrochloride N-[4-(5-Dimethylamino-2,3,4,5-tetrahydro-1-benzazepine-1-carbonyl)phenyl]-2-methylbenzamide hydrochloride OPC 31260 hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 464.01 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).

As a certified reference material (CRM), 138470-70-9 5-(Dimethylamino)-1-[4-(2-methylbenzamido)benzoyl]-2,3,4,5-tetrahydro-1H-benzazepine hydrochloride Mozavaptan hydrochloride N-[4-(5-Dimethylamino-2,3,4,5-tetrahydro-1-benzazepine-1-carbonyl)phenyl]-2-methylbenzamide hydrochloride OPC 31260 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.
