Chemical Structure

S 421 CAS 127-90-2 chemical structure

Description

S 421 (CAS 127-90-2) is a high-purity analytical reference standard with the molecular formula C6H6Cl8O and a molecular weight of 377.74 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, S 421 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.74 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.

CATO manufactures S 421 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
