Chemical Structure
Description
The occurrence of (1-Methylheptyl)phosphonic Acid is closely related to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1-Methylheptyl)phosphonic Acid (CAS 4730-70-5), molecular formula C8H19O3P and molecular weight 194.21 g/mol, is a CATO reference standard with documented purity and traceability.
(1-Methylheptyl)phosphonic Acid (C8H19O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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), (1-Methylheptyl)phosphonic 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.
