Chemical Structure

2,2-Difluorobutane-1,4-diol CAS 108781-20-0 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 2,2-Difluorobutane-1,4-diol.

CATO supplies 2,2-Difluorobutane-1,4-diol (CAS 108781-20-0), a certified reference material (molecular formula C4H8F2O2, MW 126.10 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2,2-Difluorobutane-1,4-diol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.10 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.

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), 2,2-Difluorobutane-1,4-diol 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.
