Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including PTP Inhibitor III (4-(Bromoacetyl)phenoxyacetic Acid).
PTP Inhibitor III (4-(Bromoacetyl)phenoxyacetic Acid) (CAS 29936-81-0) is a high-purity analytical reference standard with the molecular formula C10H9BrO4 and a molecular weight of 273.08 g/mol.
PTP Inhibitor III (4-(Bromoacetyl)phenoxyacetic Acid) (C10H9BrO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), PTP Inhibitor III (4-(Bromoacetyl)phenoxyacetic Acid) 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.
