Chemical Structure
Description
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tris(hydroxymethyl)aminomethane-ethylendiaminetetraacetic acid mixt. is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 413.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Tris(hydroxymethyl)aminomethane-ethylendiaminetetraacetic acid mixt. (CAS 38641-82-6) is a high-purity analytical reference standard with the molecular formula C10H16N2O8C4H11NO3 and a molecular weight of 413.38 g/mol.
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 Tris(hydroxymethyl)aminomethane-ethylendiaminetetraacetic acid mixt. 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.
