Description
CATO manufactures 2-Methylcyclohexanecarboxylic anhydide 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-Methylcyclohexanecarboxylic anhydide (CAS 1263376-39-1) is a high-purity analytical reference standard with the molecular formula C16H26O3 and a molecular weight of 266.38 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2-Methylcyclohexanecarboxylic anhydide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
