Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl 5,5-dimethyl-1-oxaspiro[2.5]octane-2-carboxylate.
Methyl 5,5-dimethyl-1-oxaspiro[2.5]octane-2-carboxylate (CAS 1492760-49-2), molecular formula C11H18O3 and molecular weight 198.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Methyl 5,5-dimethyl-1-oxaspiro[2.5]octane-2-carboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 198.26 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Methyl 5,5-dimethyl-1-oxaspiro[2.5]octane-2-carboxylate 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.
