Benzene, 1-bromo-4-(pentylthio)- CAS 139996-18-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzene, 1-bromo-4-(pentylthio)-.

Benzene, 1-bromo-4-(pentylthio)- (CAS 139996-18-2) is a high-purity analytical reference standard with the molecular formula C11H15BrS and a molecular weight of 259.21 g/mol.

Owing to sulfur-containing functionality, bromine substitution, an aromatic ring system, Benzene, 1-bromo-4-(pentylthio)- is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 259.21 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
