Chemical Structure

Di-tert-butyl sulfite CAS 166093-55-6 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Di-tert-butyl sulfite.

Di-tert-butyl sulfite (CAS 166093-55-6), molecular formula C8H18O3S and molecular weight 194.29 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Di-tert-butyl 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.

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

As a certified reference material (CRM), Di-tert-butyl sulfite meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
