JWH-398 CAS 1292765-18-4

Description

Compared with other compounds in its class, the molecular weight of 375.89 g/mol gives JWH-398 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

JWH-398 (CAS 1292765-18-4) is a high-purity analytical reference standard with the molecular formula C24H22ClNO and a molecular weight of 375.89 g/mol.

Structurally, JWH-398 (C24H22ClNO) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 375.89 g/mol, it falls into the moderately-high-molecular-weight range. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
