Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 260.29 g/mol gives METHYL 4-(PHENYLBUTA-1,3-DIYN-1-YL)BENZOATE distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
METHYL 4-(PHENYLBUTA-1,3-DIYN-1-YL)BENZOATE (CAS 297178-34-8), molecular formula C18H12O2 and molecular weight 260.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of METHYL 4-(PHENYLBUTA-1,3-DIYN-1-YL)BENZOATE (C18H12O2) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures METHYL 4-(PHENYLBUTA-1,3-DIYN-1-YL)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.
