Tetrabutyl 1,3-trimethylenediphosphonate CAS 64630-19-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tetrabutyl 1,3-trimethylenediphosphonate.

Tetrabutyl 1,3-trimethylenediphosphonate (CAS 64630-19-9), molecular formula C19H42O6P2 and molecular weight 428.48 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tetrabutyl 1,3-trimethylenediphosphonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 428.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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), Tetrabutyl 1,3-trimethylenediphosphonate 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.
