[2,3'-bithiophene]-5'-carbaldehyde CAS 893736-91-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including [2,3'-bithiophene]-5'-carbaldehyde.

[2,3'-bithiophene]-5'-carbaldehyde (CAS 893736-91-9), molecular formula C9H6OS2 and molecular weight 194.27 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of [2,3'-bithiophene]-5'-carbaldehyde (C9H6OS2) is characterized by sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 [2,3'-bithiophene]-5'-carbaldehyde 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.
