Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Dibutyl Sulfite (CAS 626-85-7), a certified reference material (molecular formula C8H18O3S, MW 194.29 g/mol) for analytical method development and quality control.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Dibutyl Sulfite is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
CATO manufactures Dibutyl Sulfite 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.
