propyl 5-bromothiophene-3-carboxylate CAS 1478954-26-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including propyl 5-bromothiophene-3-carboxylate.

propyl 5-bromothiophene-3-carboxylate (CAS 1478954-26-5), molecular formula C8H9BrO2S and molecular weight 249.12 g/mol, is a CATO reference standard with documented purity and traceability.

propyl 5-bromothiophene-3-carboxylate (C8H9BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

As a certified reference material (CRM), propyl 5-bromothiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
