(E)-4-Oxo-4-((tributylstannyl)oxy)but-2-enoic acid CAS 4027-18-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-Oxo-4-((tributylstannyl)oxy)but-2-enoic acid.

(E)-4-Oxo-4-((tributylstannyl)oxy)but-2-enoic acid (CAS 4027-18-3), molecular formula C12H27SnC4H3O4 and molecular weight 405.12 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (E)-4-Oxo-4-((tributylstannyl)oxy)but-2-enoic acid (C12H27SnC4H3O4) is characterized by a carboxylic acid group, 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 (E)-4-Oxo-4-((tributylstannyl)oxy)but-2-enoic acid 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.
