Description
CATO manufactures 2,2-Dimethyl-3-butynoic Acid 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.
2,2-Dimethyl-3-butynoic Acid (CAS 56663-76-4), molecular formula C6H8O2 and molecular weight 112.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2,2-Dimethyl-3-butynoic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 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.
