Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 2-chloro-3,3-dimethylbutanoate (CAS 98551-46-3) is a high-purity analytical reference standard with the molecular formula C8H15ClO2 and a molecular weight of 178.66 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-chloro-3,3-dimethylbutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 178.66 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.
CATO manufactures Ethyl 2-chloro-3,3-dimethylbutanoate 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.
