Description
CATO manufactures (E)-methyl 4-(2-chloro-4-methoxystyryl)benzoate 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.
(E)-methyl 4-(2-chloro-4-methoxystyryl)benzoate (CAS 1268246-22-5) is a high-purity analytical reference standard with the molecular formula C17H15ClO3 and a molecular weight of 302.75 g/mol.
Structurally, (E)-methyl 4-(2-chloro-4-methoxystyryl)benzoate (C17H15ClO3) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 302.75 g/mol, it falls into the moderately-high-molecular-weight range. 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.
