Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Isobutylene Sulfide.
CATO supplies Isobutylene Sulfide (CAS 3772-13-2), a certified reference material (molecular formula C4H8S, MW 88.17 g/mol) for analytical method development and quality control.
Structurally, Isobutylene Sulfide (C4H8S) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 88.17 g/mol, it falls into the low-molecular-weight range.
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.
