Chemical Structure

8-Methyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine dihydrochloride CAS 956431-48-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Methyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine dihydrochloride.

8-Methyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine dihydrochloride (CAS 956431-48-4) is a high-purity analytical reference standard with the molecular formula C9H12N2OHCl and a molecular weight of 200.67 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 8-Methyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine dihydrochloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.67 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).

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.

As a certified reference material (CRM), 8-Methyl-2,3,4,5-tetrahydropyrido[3,2-f][1,4]oxazepine dihydrochloride 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.
