1,4-Butane-d8-dithiol CAS 1219805-46-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Butane-d8-dithiol.

1,4-Butane-d8-dithiol (CAS 1219805-46-5) is a high-purity analytical reference standard with the molecular formula C4H2D8S2 and a molecular weight of 130.30 g/mol.

Structurally, 1,4-Butane-d8-dithiol (C4H2D8S2) contains deuterium isotope labeling, sulfur-containing functionality. 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 130.30 g/mol, it falls into the low-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.
