Chemical Structure
Description
Ethyl 2-chloro-3-methylbutanoate (CAS 91913-99-4), molecular formula C7H13ClO2 and molecular weight 164.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Ethyl 2-chloro-3-methylbutanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 164.63 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 Ethyl 2-chloro-3-methylbutanoate 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.
