Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 256.73 g/mol gives Mcpa-1-Butyl Ester distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Mcpa-1-Butyl Ester (CAS 1713-12-8), molecular formula C13H17ClO3 and molecular weight 256.73 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, an aromatic ring system, Mcpa-1-Butyl Ester is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.73 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.
CATO manufactures Mcpa-1-Butyl Ester 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.
