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 Isopropyl ethylenesulfonate.
CATO supplies Isopropyl ethylenesulfonate (CAS 3851-91-0), a certified reference material (molecular formula C5H11O6S2, MW 231.27 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, a sulfone group, Isopropyl ethylenesulfonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
As a certified reference material (CRM), Isopropyl ethylenesulfonate 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.
