Chemical Structure
Description
3-Chloro-2-methylbutan-2-ol (CAS 21326-62-5) is a high-purity analytical reference standard with the molecular formula C5H11ClO and a molecular weight of 122.59 g/mol.
Owing to a hydroxyl group, an ether linkage, chlorine substitution, 3-Chloro-2-methylbutan-2-ol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 122.59 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.
CATO manufactures 3-Chloro-2-methylbutan-2-ol 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.
