Description
CATO manufactures ethyl 2-chloro-4-methylpentanoate 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.
ethyl 2-chloro-4-methylpentanoate (CAS 78968-28-2), molecular formula C8H15ClO2 and molecular weight 178.66 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-4-methylpentanoate 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
