Description
CATO manufactures Methyl 3-methyl-5-oxo-5-(thiophen-2-yl)pentanoate 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.
Methyl 3-methyl-5-oxo-5-(thiophen-2-yl)pentanoate (CAS 14811-68-8), molecular formula C11H14O3S and molecular weight 226.29 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, Methyl 3-methyl-5-oxo-5-(thiophen-2-yl)pentanoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 226.29 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
