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-oxaspiro[4.4]nonan-3-yl}methanesulfonyl chloride.
CATO supplies {2-oxaspiro[4.4]nonan-3-yl}methanesulfonyl chloride (CAS 2091454-01-0), a certified reference material (molecular formula C9H15ClO3S, MW 238.73 g/mol) for analytical method development and quality control.
{2-oxaspiro[4.4]nonan-3-yl}methanesulfonyl chloride (C9H15ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
CATO manufactures {2-oxaspiro[4.4]nonan-3-yl}methanesulfonyl chloride 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.
