1-Methyl-1,4-diazepan-5-one hydrochloride CAS 854828-87-8

Description

The occurrence of 1-Methyl-1,4-diazepan-5-one hydrochloride is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Methyl-1,4-diazepan-5-one hydrochloride (CAS 854828-87-8), molecular formula C6H12N2OHCl and molecular weight 164.63 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 1-Methyl-1,4-diazepan-5-one hydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 1-Methyl-1,4-diazepan-5-one 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.
